IT MAY NOT LOOK LIKE IT,
BUT WE'RE PROFESSIONALS.

DO US A FAVOR.

DON'T TRY THIS AT HOME!
WHOA!

Narrator: ON THIS EPISODE
OF "MYTHBUSTERS"...

ONLY ON "MYTHBUSTERS" IS SOMEONE
TRANSFERRED ON A STRETCHER

TO BE DROPPED OFF
A BUILDING.

...ADAM AND JAMIE
JUMP ON THE MYTH

OF AN INNER SPRING FLING.

THAT WAS JUST AS MUCH FUN
AS IT SEEMED LIKE.

IF A 3-STORY DROP
INTO SHALLOW WATER IS LETHAL...

OH!

...COULD YOU CUSHION
THE SAME FALL WITH A MATTRESS...

I FEEL LIKE I JUST GOT SPANKED.

Narrator: ...AND LIVE
TO LEAP ANOTHER DAY?

I'M SCREWED.

MEANWHILE,
KARI, TORY, AND GRANT...

TIME FOR BATTLE.

...PUT THEIR BOULDERS
TO THE GRINDSTONE...

I LIKE-A TO CALL THIS A-PIECE
"BALL ON THE BRICK."

Narrator: ...ROCKING THE MYTH
THAT 15th-CENTURY CANNONEERS...

I LOVE THAT ECHO
IN THE CANYON.

Narrator:
...FIRED STONE CANNONBALLS.

Kari: 1.

Narrator: COULD THEY REALLY DO
AS MUCH DAMAGE AS METAL

AND LEAVE NOTHING FOR THE ENEMY
TO FIRE BACK?

THAT IS THE MOST DISTURBING
CASTLE I'VE EVER SEEN.

Narrator:
WHO ARE THE MYTHBUSTERS?

ADAM SAVAGE...

IT'S SCIENTIFIC!

...AND JAMIE HYNEMAN.

WELL, THERE'S YOUR PROBLEM.

BETWEEN THEM, MORE THAN 30 YEARS
OF SPECIAL EFFECTS EXPERIENCE.

TOGETHER WITH TORY BELLECI...

THAT WAS INSANE.

...KARI BYRON...

FREAKIN' CONFIRMED!

...AND GRANT IMAHARA...

DECAPITATION HAZARD, EVERYBODY.

Narrator: ...THEY DON'T JUST
TELL THE MYTHS,

THEY PUT THEM TO THE TEST.

OKAY, SO, WE'RE STARTING OFF
WITH SOMETHING A BIT DIFFERENT.

THAT'S RIGHT. WE'RE STARTING OFF
WITH AN APOLOGY,

BECAUSE IT WAS DURING
THE FILMING OF THIS EPISODE

THAT A CANNONBALL ACCIDENTALLY
WENT THROUGH SOMEONE'S HOUSE.

YEAH, I MEAN, WE TAKE SAFETY
VERY SERIOUSLY ON OUR SHOW,

AND DESPITE A WHOLE ARRAY
OF SAFETY PRECAUTIONS

AT THE BOMB RANGE,
WE HAD A MAJOR MISHAP.

A MISHAP WHERE
WE'RE TREMENDOUSLY RELIEVED

THAT NO ONE GOT HURT,

BUT WE'RE ALSO TREMENDOUSLY
SORRY THAT IT HAPPENED AT ALL.

AND WITH THAT,
LET'S START OUR SHOW.

Narrator:
OKAY, SO, FIRST UP

A MYTH THAT'S ALL ABOUT
SOFT LANDINGS.

PLAYING WITH DOLLS AGAIN,
ARE WE?

NO, NO, NO.
I'M SETTING UP A SCENARIO.

FOR WHAT?

ALL RIGHT,
LET ME WALK YOU THROUGH IT.

PICTURE YOURSELF
IN A HOTEL ROOM,

AND YOU ARE
IN MORTAL DANGER

BECAUSE THERE'S SOME GUYS
BANGING ON THE DOOR

WHO WANT TO SHOOT YOU.

NOW, YOU CAN'T, OBVIOUSLY, LEAVE
THROUGH THE NORMAL MEANS

LIKE THE DOOR.

YOU'VE GOT TO LEAVE
BY JUMPING OFF YOUR BALCONY.

UNFORTUNATELY,
YOUR BALCONY,

IT'S 35 FEET
ABOVE THE GROUND.

FORTUNATELY, HOWEVER, THERE IS
A SWIMMING POOL BELOW YOU.

UNFORTUNATELY,

THAT SWIMMING POOL
IS ONLY 4 1/2 FEET DEEP.

THAT COULD GET UGLY.

VERY UGLY.

THIS COMES FROM THE SHOW
"BURN NOTICE,"

AND WHAT OUR HERO IS EXPLAINING
TO THE AUDIENCE

AS HE THROWS A MATTRESS
OUT THE WINDOW

AND INTO THE POOL,

AND THEN HE JUMPS INTO
THE MATTRESS TO SAFETY.

SO THE MYTH IS THAT IF YOU NEED
TO JUMP INTO A SHALLOW POOL

FROM A HEIGHT YOU SHOULD THROW
A MATTRESS DOWN THERE FIRST.

I COULDN'T HAVE SAID IT
BETTER MYSELF.

Narrator: ACCORDING TO
THIS "BURN NOTICE" MYTH,

THERE'S NO WAY
YOU COULD LEAP AND LIVE

AFTER A 35-FOOT DROP
INTO SHALLOW WATER.

HOWEVER, BREAKING YOUR FALL
WITH A MATTRESS

COULD SUPPOSEDLY SAVE YOUR BUTT.

SO, WOULD A CRASH LANDING
REALLY LEAVE YOU

WITH MORE OF A SPRING IN YOUR
STEP THAN A SPLASH LANDING?

SO, HOW DO YOU WANT
TO TEST THIS?

WELL, CLEARLY
THE MAIN THING HERE

IS TO TEST WHAT IT'S LIKE TO
JUMP ONTO A MATTRESS IN A POOL,

BUT WE NEED TO COMPARE THAT

TO WHAT IT WOULD BE LIKE JUST
JUMPING INTO THE POOL AS WELL.

YEAH, INDEED, AND WE'RE GOING
TO NEED A POOL

THAT IS EXACTLY
4 1/2 FEET DEEP.

WELL, LET'S GET A CRANE
AND SOME DUMMIES

AND ATTACH SOME SENSORS TO THEM
AND DROP THEM OFF.

SEE WHAT HAPPENS.

THAT'S PERFECT.
LET'S DO IT.

SO, IT'S STRAIGHT
TO THE SHALLOW END

AT DEFREMERY POOL IN OAKLAND.

IT'S A NICE POOL.

IT OUGHT TO WORK.

LET'S SEE IF WE CAN GET
BUSTER HURT.

WHERE THEY'LL HOIST BUSTER UP
FOR THIS 3-STORY STORY.

IT TURNS OUT ONE OF THE MOST
DIFFICULT PART OF THIS SHOOT

IS JUST GETTING THE GRADALL
INTO THE POOL AREA.

IT'S A BIT
OF A TIGHT SQUEEZE.

THIS WHOLE STORY
COMES DOWN TO,

IF YOU HAVE 35 FEET TO JUMP

AND YOU'VE GOT A POOL BELOW YOU
THAT'S ONLY 4 1/2 FEET DEEP,

IS IT BETTER TO JUMP
INTO THE REGULAR POOL

OR ONTO A MATTRESS
FLOATING IN THAT POOL?

OF ALL THE DROPS
THAT BUSTER'S GOING TO DO,

WE'RE GOING TO WANT TO MAKE SURE
WE KNOW HOW HARD HE'S DROPPING,

AND THAT'S WHERE THIS
COMES INTO PLAY.

THIS IS AN ACCELEROMETER,

AND JUST LIKE
A CRASH-TEST DUMMY,

I'M GOING TO INSTALL THIS
IN BUSTER'S CHEST

TO LET US KNOW HOW MANY Gs
HE PULLS

ON EACH OF THE SURFACES
WE'RE DROPPING HIM ON.

Narrator: WITH AN ACCELEROMETER
HEART TO TRACK HIS IMPACT...

LET'S CLOSE HIM UP.

...THE PVC MAN IS READY
FOR THE DROP.

ONLY ON "MYTHBUSTERS" IS SOMEONE
TRANSFERRED ON A STRETCHER

TO BE DROPPED OFF A BUILDING.

Narrator:
HOWEVER, FIRST HE NEEDS

TO ADOPT THE "BURN NOTICE"
POSITION.

Adam: NOW, IN THE SHOW
OUR CHARACTER STATES

THAT PROPERLY DISTRIBUTING
YOUR WEIGHT,

I.E. LANDING BUTT FIRST
ONTO A MATTRESS ON THE WATER,

IS THE SAFEST WAY
TO JUMP INTO THE POOL.

Narrator: SO, BUSTER WILL JUMP
BUTT FIRST.

BUT FIRST UP, BUSTER WILL TAKE
THE PLUNGE WITHOUT A MATTRESS.

SO, WHAT KIND OF DAMAGE
WILL THAT DROP DO?

Adam: HERE WE GO, BUSTER.
TIME TO JUMP INTO THE POOL.

Jamie: OKAY, DROPPING BUSTER
INTO THE WATER

FROM 35 FEET IN 3, 2, 1, GO!

[ LAUGHS ]

THAT WAS JUST AS MUCH FUN
AS IT SEEMED LIKE.

Narrator:
BUSTER TOOK THE FALL,

AND HIS BACKSIDE TOOK A WALLOP,

FROM BOTH THE WATER
AND THE BOTTOM OF THE POOL.

BUT WHAT DOES THE DATA SAY?

Jamie: SO, WE DROPPED
OUR DUMMY FROM 35 FEET

STRAIGHT INTO THE WATER,

AND WE SAW AN INITIAL IMPACT
OF 50 Gs,

FOLLOWED BY AN IMPACT ALONG
THE BOTTOM OF THE POOL OF 29 Gs.

NOW, 50 Gs IS OUR THRESHOLD
FOR POTENTIAL DEATH.

ONE WAY OR ANOTHER,

YOU'RE NOT WALKING AWAY
FROM AN IMPACT LIKE THAT.

Narrator: YEP, THERE'S NO
WALKING AWAY FROM THAT.

BUT HOW WILL IT COMPARE
WITH THE MYTH?

CAN THE AVERAGE MATTRESS...

FOR OUR MATTRESS TEST,

WE'VE CHOSEN A STANDARD
INNER SPRING MATTRESS.

THAT'S THIS ONE RIGHT HERE.

Narrator: ...REALLY MAKE
A FATAL FLOP SURVIVABLE?

PERFECT.

OKAY. 3, 2, 1, GO!

NICE.

"X" MARKS THE SPOT.

BUSTER HIT
WITH AN AUDIBLE IMPACT.

BUT DID THE MATTRESS
CUSHION HIS TUSH?

Adam:
BUSTER'S DROP WAS PERFECT,

AND ALTHOUGH HE MIGHT NOT
LOOK LIKE IT,

ACCORDING TO OUR
ACCELEROMETER DATA,

HE IS A FRIGGING MESS.

HE PULLED 86 Gs
HITTING THAT MATTRESS,

ROUGHLY EQUIVALENT
TO A SEVERE CAR ACCIDENT.

AND THAT WAS SUPPOSED TO BE
THE SAFE JUMP.

IT'S NOT LOOKING VERY GOOD
FOR THIS STORY.

Narrator:
IT'S NOT LOOKING GOOD

BECAUSE THAT'S A MORE DAMAGING
IMPACT THAN ONTO WATER ALONE.

HOWEVER...

Adam: WELL, I LOVE
OUR ACCELEROMETER DATA

FROM ALL THESE DROPS,

BUT I CAN'T HELP
FEELING LIKE

THEY'RE NOT GIVING US
THE FULL PICTURE.

I'D LOVE IN SOME WAY TO BE ABLE
TO SEE WHAT KIND OF INJURIES

BUSTER MIGHT TAKE
FROM THAT KIND OF FALL.

I KNOW WHAT YOU MEAN,
AND I MIGHT HAVE JUST THE THING.

NEXT UP, A MYTH ON THE ROCKS.

OKAY, SO OUR NEXT MYTH
IS A GREAT ONE

THAT COMES
FROM THE 15th CENTURY.

AWESOME.
WHAT'S THE STORY?

WELL, IT'S ABOUT CANNONS,

OR MORE SPECIFICALLY,
ABOUT THE CANNONBALLS.

SO THE EUROPEAN CANNONEERS
AT THE TIME

WERE RELUCTANT TO FIRE THEIR
CANNONS ON THE BATTLEFIELD

FOR TWO REASONS.

I GUESS ONE REASON WOULD BE

SO THEY COULDN'T RETRIEVE
THE CANNONBALLS

AND FIRE THEM BACK.

SO I GUESS THE OTHER REASON
COULD BE THAT,

CAST IRON WAS A PRETTY VALUABLE
COMMODITY BACK THEN,

SO YOU COULD MELT DOWN
THE CANNONBALLS

AND MAKE YOUR OWN CANNONS.

EXACTLY.

SO, THE MYTH IS THAT,
INSTEAD OF FIRING

THEIR CAST-IRON
CANNONBALLS,

THEY MADE THEIR OWN CANNONBALLS
OUT OF STONE

AND FIRED THEM TO HAVE
EQUIVALENT DAMAGE

TO THE CAST IRON,
YET EXPLODE ON IMPACT

SO THEY COULDN'T BE SENT BACK
OR MELTED DOWN.

INTERESTING.
THAT IS BRILLIANT.

Narrator: ON THE BATTLEFIELDS
OF 15th-CENTURY EUROPE,

SOME CANNY CANNONEERS

DIDN'T WANT TO GIVE THE ENEMY
ANY AMMUNITION.

SO, SUPPOSEDLY THEY FASHIONED
THEIR CANNON FODDER OUT OF ROCK.

BUT WOULD A STONE CANNONBALL
REALLY DO AS MUCH DAMAGE

AS METAL
AND EXPLODE ON IMPACT?

OKAY, SO, ULTIMATELY
WE'RE GOING TO HAVE TO BUILD

A CASTLE OF SOME KIND

AND COMPARE THE DAMAGE DONE
BY CAST IRON

AND STONE CANNONBALLS.

WHICH MEANS WE'RE GOING TO HAVE
TO MAKE SOME STONE CANNONBALLS,

BUT ALSO WE'RE GOING TO HAVE
TO GET HOLD OF A CANNON.

WELL, WE DO KNOW SOMEBODY WHO
HAS THE PERFECT ANTIQUE CANNON.

WE CAN JUST CALL UP
HARRY WEBB

AND SEE IF HE'LL LET US USE
OLD MOSES.

YEAH,
BUT SOMETHING TELLS ME

HE'S NOT GOING TO BE
TOO HAPPY ABOUT US

FIRING STONE CANNONBALLS
THROUGH OLD MOSES.

WHAT IF WE BREAK IT?

WELL, WE COULD USE
THE SMALL CANNON THAT I BUILT

FOR THE "BALL AND CHAIN"
PRISON ESCAPE.

GOOD IDEA, BUT YOU KNOW
WE'VE NEVER ACTUALLY FIRED THAT

AT GENUINE BATTLE SPEEDS.

SO MAYBE WE USE OLD MOSES

TO GET THE TRUE FIRING SPEED
OF A CANNONBALL.

THEN WE CALIBRATE YOUR CANNON TO
MATCH THAT AND GO FROM THERE.

GREAT.

Narrator: YEP, BEFORE ANYONE
CASTS THE FIRST STONE,

THE MYTHBUSTERS
HEAD TO THE BOMB RANGE.

Kari:
WE'VE SAFELY FIRED OUR CANNON
SEVERAL TIMES ON THE SHOW.

WE USED IT FOR
THE "BALL AND CHAIN" MYTH.

WE'VE ACTUALLY FIRED CHEESE
FROM IT...

BUT WE'VE NEVER ACTUALLY
HAD TO FIRE ANYTHING

AT WHAT YOU WOULD CALL
BATTLE SPEEDS.

SO THAT'S WHAT WE NEED
TO FIND OUT FIRST.

HOW FAST DOES A STEEL CANNONBALL
TRAVEL FROM A REAL CANNON?

AND ONCE WE KNOW THAT,

WE CAN CALIBRATE THIS CANNON
TO MATCH ITS SPEED.

Narrator: BUT BEFORE ANY
CANNON CALIBRATION,

THEY'RE PULLING OUT
ALL THE STOPS

TO CREATE A ROCK-SOLID BARRICADE

TO STOP THE CANNONBALL
IN ITS TRACKS.

Tory:
THAT LOOKS ABOUT PERFECT.

MEANWHILE, OLD MOSES MOSEYS UP
TO THE BOMB RANGE.

WOW!

OLD MOSES AND THE MYTHBUSTERS
GO WAY BACK.

LIVE!

IN FACT, YOU MIGHT SAY,

IT'S THE CANNON OF CHOICE
WHEN IT COMES TO MYTHBUSTING.

[ LAUGHING ]

Tory: WE'RE GOING TO FIRE
A CANNONBALL OUT OF OLD MOSES.

WE'RE GOING TO CATCH IT
ON A HIGH SPEED.

WE'RE GOING TO USE THE SCALE

TO SEE HOW FAST
THAT CANNONBALL IS GOING,

AND THEN WE'RE GOING TO MATCH
OUR CANNONBALL

TO THAT SAME SPEED.

NOW, SINCE THESE CANNONBALLS
ARE SO IMPORTANT,

WE HAVE TO FIND IT, SO WE HAVE
A CANNONBALL CATCHER.

WE HAVE THREE GARBAGE CANS
FILLED WITH WATER

IN FRONT OF A CONCRETE WALL
COVERED IN BED LINER.

THAT SHOULD SLOW
THE CANNONBALL DOWN,

AND WE'LL BE ABLE
TO RETRIEVE IT.

Narrator: BEHIND THE WALL

THERE'S ALSO A SECOND LINE
OF BARRELS,

FOR OPTIMUM
CANNONBALL CATCHING,

AND BEHIND THAT, THE ULTIMATE
SAFETY STOP, A DIRT HILLSIDE.

ONE POUND OF BLACK POWDER.

Narrator: SO NOW IT'S OVER
TO KARI TO PREP THE POWDER.

FOIL CONTAINER
TO PREVENT SPARKS.

ONE POWERFUL BURRITO.

VENT.
VENTED.

Narrator:
ONE POUND OF BLACK POWDER

IS THE BATTLE STANDARD
FOR A CANNON LIKE OLD MOSES.

AND SAFELY BEHIND
THE BLAST-PROOF SHIELDS,

IT'S THE COUNTDOWN TO
CANNONBALL CALIBRATION.

Kari: OKAY, THIS IS OLD MOSES
IN 3, 2, 1.

WHOA!
WOW.

THAT WAS ENERGETIC.

WOW!

SEE THAT BEAUTIFUL ARRAY
OF WATER?

Narrator: THE RED PLUME OF WATER
LOOKED STRIKING,

AND THE BALL CATCHERS
CAUGHT THE CANNONBALL.

SO, WE'VE GOT ONE,
TWO, THREE BARRELS.

HEY, HERE'S THE BALL.
WOW.

ALL RIGHT,
LET'S SEE HOW FAST IT WAS GOING.

THERE'S THE SHOT,
AND THERE'S THE BALL.

WHAT'S THE MUZZLE
VELOCITY?

1,200 FEET PER SECOND.

NICE.

Narrator: SO,
THAT'S THE SPEED TO MATCH,

AND IT'S OUT WITH OLD MOSES

AND IN WITH THE MYTHBUSTERS
MINIATURE CANNON.

COMING UP...

OH!

...BUSTER'S COUSIN DROPS IN.

PERFECT HIT.

AND LATER...

HOW MANY TOOLS DOES IT TAKE
TO MAKE A STONE CANNONBALL?

WE'RE GONNA FIND OUT.

Narrator:
SUPPOSEDLY A 3-STORY FALL

INTO 4 1/2 FEET OF WATER

WOULD GET YOU OFF
ON THE WRONG FOOT.

BUT IF YOU LANDED
ON A FLOATING MATTRESS,

COULD YOU ESCAPE UNSCATHED?

WELL, SO FAR, BUSTER TOOK
A LETHAL HIT ON THE MATTRESS

AND A SURVIVABLE HIT ON WATER.

AND THAT WAS SUPPOSED
TO BE THE SAFE JUMP.

IT'S NOT LOOKING VERY GOOD
FOR THIS STORY.

Narrator: HOWEVER,
TO DEFINITIVELY CALL THIS,

THEY'RE GOING TO DUMMY UP
SOMETHING MORE LIFELIKE.

REMEMBER THAT I SAID
I HAD SOMETHING

THAT WAS A LITTLE BETTER THAN
THE DUMMIES WE'D BEEN USING?

WE DO.
HEY, ADAM, CHECK THIS OUT.

OH!

Narrator: YEP, YOU MAY REMEMBER
THIS DISTURBING FACE

FROM THE HALLOWEEN SPECIAL.

ARE YOU READY FOR THE HORROR?

DUH DUH DUH DUH!

Narrator:
BUT ITS ROLE AS JOHN DOE

HID THE SYNDAVER'S
REAL PURPOSE....

TO THE WINDOW!

Narrator: ...AS AN ULTRA
REALISTIC HUMAN ANALOGUE.

THESE ARE SURGICAL
TRAINING DUMMIES.

THEY'RE MADE
MUSCLE BY MUSCLE,

AND THEY'RE ACTUALLY
SUTURED IN PLACE.

OH, MY GOD.

I DARE SAY THAT IT'S
ABSOLUTELY BEAUTIFUL.

THIS IS
MEDICALLY ACCURATE?

IT IS.
IT'S MADE OF A POLYMER.

IT'S WATER BASED,

AND EVERYTHING
IS AS REALISTIC

AS MODERN TECHNOLOGY
CAN MAKE IT.

AND ITS ANATOMY ISN'T THE ONLY
THING THAT'S REALISTIC.

I WISH YOU WERE HERE
BECAUSE IT'S BEAUTIFUL

AND IT SMELLS KIND OF BAD,
WHICH YOU'D EXPECT.

BUT BEFORE THE SYNDAVER
CAN TAKE THE PLUNGE,

JAMIE NEEDS TO GIVE IT A SKIN.

AND THIS SHRINK-WRAPPING
ALSO DOUBLES AS WATERPROOFING.

READY FOR MARKET?

Narrator: SO, WITH
THE SYNDAVER SKINNED UP,

IT'S TIME TO DROP IT OFF
AT THE POOL.

YOU FEELING READY, BUDDY?

Jamie: ONE OF THE NICE THINGS
ABOUT USING

THIS PARTICULAR TYPE OF DUMMY

IS THAT, WITH THE HELP
OF A PORTABLE X-RAY MACHINE

LIKE THIS DEVICE OVER HERE,

WE CAN ACTUALLY FIGURE OUT WHAT
HAPPENED INTERNALLY TO THE DUMMY

WITHOUT PERFORMING
THE EQUIVALENT OF AN AUTOPSY.

Narrator:
SO, AFTER A CHECK-UP

TO MAKE SURE EVERYTHING
IS WHERE IT SHOULD BE...

Man: YOU CAN SEE THAT THE RIBS
COME ACROSS.

THEY'RE ALL INTACT.

YOU CAN SEE ALL
THE CERVICAL VERTEBRAE.

Narrator: ...IT'S TIME
TO STRAP UP THE SYNBUSTER

FOR ITS FIRST FALL
INTO 4 1/2 FEET OF WATER.

Jamie: SYNDAVER INTO THE POOL
FROM 35 FEET

IN 3, 2, 1, GO!

A PERFECT HIT.

IT'S BOTTOMS UP
FOR THE NEW BUSTER...

...BUT WHAT KIND OF DAMAGE
DID THAT DROP DO?

WELL, TO FIND OUT, IT'S FISHED
OUT FOR A CLOSER EXAMINATION

BY BOTH THE X-RAY AND AN EXPERT.

NOW THAT WE'VE DROPPED
OUR DUMMY,

WE WOULD REALLY LIKE TO GET
AN EXPERT OPINION

ON EXACTLY HOW MUCH DAMAGE
IT SUSTAINED,

AND WE'D LIKE AN EXPERT THAT
DEALS WITH THIS KIND OF INJURY

EVERY SINGLE DAY,

AND THAT'S CALLED
AN ORTHOPAEDIC SURGEON.

WE FOUND ONE
NAMED DR. NOAH WEISS.

DR. WEISS,
ARE YOU WILLING TO GIVE US

A FREE CONSULT
ON BUSTER'S INJURIES?

SURE, I'D BE HAPPY TO.

LET'S GO TAKE A LOOK.

WE CAN SEE OVER HERE IS THERE'S
ACTUALLY BEEN A SEPARATION

BETWEEN THE LUMBAR SPINE
AND THE SACRUM.

THIS IS A VERY SEVERE INJURY

THAT WOULD MOST CERTAINLY RESULT
IN MAJOR SPINAL CORD DAMAGE.

WOW.

SO, OUR DUMMY'S PARALYZED.

IT'S PARALYZED.

Adam: SO, OUR SYNDAVER,

AFTER BEING DROPPED
INTO THE POOL

WITHOUT A MATTRESS IN ITS WAY

HAS SUSTAINED
SOME VERY SERIOUS DAMAGE --

A SHATTERED PELVIS AND
A PARALYZING SPINE INJURY,

AND IF IT SEEMS LIKE
I'M SMILING,

I'M ONLY HAPPY THAT WE GOT
SOME SIGNIFICANT RESULTS

FROM THIS DUMMY.

NOW WE'RE GOING TO DROP ONE
INTO A MATTRESS.

Narrator: IN THEIR PREVIOUS TEST
WITH THE ORIGINAL BUSTER,

THE G LOAD OF THE DROP
ONTO A MATTRESS WAS HIGHER.

BUT WILL THAT MEAN
THAT SYNBUSTER TWO

SUSTAINS MORE INJURY BY MAKING
A BED AND LEAPING INTO IT?

READY, ADAM?
READY.

3, 2, 1, GO.

PERFECT HIT.

Narrator:
BUSTER HIT THE CRASH PAD,

AND ITS BUTT TOOK THE BRUNT.

SO IT'S OVER TO DR. WEISS

TO FIND OUT IF THE SYNBUSTER'S
REAR IS IN THE CLEAR.

ON PHYSICAL EXAMINATION,

WHAT'S IMMEDIATELY APPARENT IS
THE PELVIS IS FAR MORE UNSTABLE

COMPARED TO
THE PREVIOUS SYNDAVER.

REALLY?

YEAH, THIS IS
COMPLETELY DISRUPTED.

WOW.

Narrator:
AND THAT'S NOT ALL.

AS THE X-RAYS REVEAL,

THE MATTRESS JUMPER SUSTAINED
FAR MORE DAMAGE ALL OVER.

IN ADDITION TO
A SIMILAR INJURY

WHERE HE BASICALLY BLEW APART
HIS PELVIS,

THIS ONE ALSO APPEARS TO HAVE
TWO INJURIES TO HIS SPINE --

ONE IN THE LUMBAR SPINE
OR LOW BACK

AND ONE IN THE MID BACK
OR THORACIC SPINE.

HE DISLOCATED HIS KNEE.

HE DISLOCATED HIS ELBOW,

AND THE INJURY TO THE PELVIS
WAS MUCH WORSE

THAN IN THE FIRST
SYNDAVER.

SO, THE MATTRESS WAS FAR WORSE
THAN FALLING INTO WATER?

I THINK BOTH JUMPS
WERE A PROBLEM,

BUT IT DEFINITELY
APPEARS TO BE MUCH WORSE

LANDING ON THE MATTRESS
IN THE WATER.

SO HE'S EVEN MORE DEAD?

HE WOULD BE EVEN MORE DEAD
THAN THE FIRST ONE.

IS THAT A MEDICAL TERM?

IT IS NOW.

[ Chuckling ] OKAY.

Adam: WE HAVE TESTED THIS THING
SIX WAYS TO SUNDAY --

ACTUALLY,
FOUR WAYS AND ON WEEKDAYS --

BUT WE HAVE FOUND THAT, YES,

JUMPING FROM 35 FEET IS BAD
INTO WATER,

BUT INTO MATTRESS
IT'S LIKE TWICE AS BAD.

THIS IS A COUNTERINTUITIVE
RESULT,

WHICH FOR US IS TOTALLY AWESOME.

Narrator: YEP, BOTH BUSTER AND
SYNBUSTER TELL THE SAME STORY.

DESPITE WHAT YOU'D EXPECT,

A MATTRESS DOESN'T CUSHION
A SPLASH LANDING.

IT ONLY MAKES IT WORSE.

SO, WHERE WOULD YOU SAY
THIS MYTH STANDS?

YOU KNOW, IT'S ON THE TIP
OF MY TONGUE,

BUT I CAN'T QUITE --
WHAT IS IT, NOT RIGHT...

NOT TRUTHFUL.

ILL-CONCEIVED.

ILL CONCEIVED, IMPROPER,

UH, LET'S SAY,
LET'S SAY, JUST WRONG.

OKAY, IT'S WRONG.

BUT YOU KNOW
WHAT BOTHERS ME IS THAT

PEOPLE HAVE ACTUALLY BEEN KNOWN
TO DIVE FROM THAT HEIGHT

INTO SHALLOW WATER
AND SURVIVE.

I'VE BEEN THINKING
ABOUT THAT,

AND I THINK WHAT WE COULD DO
IS FIND SOMEONE

WHO KNOWS HOW TO SAFELY
JUMP FROM THOSE HEIGHTS

INTO SHALLOW WATER AND HAVE THEM
SHOW US THE METHOD.

I THINK THAT'D BE
A GOOD THING TO KNOW.

LET'S DO IT.
OKAY.

Narrator:
THE MYTH IS BUSTED,

BUT IS THERE ANY WAY
TO GET THE DROP ON A FALL

INTO 4 1/2 FEET OF WATER?

COMING UP ON "MYTHBUSTERS,"

FOR THE FIRST TIME
IN 400 YEARS,

WE FIRE CANNON BALLS...
MADE OF STONE.

Narrator: BETWEEN A ROCK
AND A HARD PLACE,

SUPPOSEDLY SOME
15th-CENTURY CANNONS

FIRED ROCKS INSTEAD OF IRON

BECAUSE NOT ONLY DID THEY DO
THE SAME DAMAGE,

THEY ALSO BROKE UP ON IMPACT.

BUT BEFORE THEY GET
TO THE STONE,

FIRST THE MYTHBUSTERS NEED
TO CALIBRATE THE MINI CANNON.

TIME FOR THE LITTLE GUNS.

JUST LIKE OLD MOSES,

THE MINIATURE CANNON FACES OFF

AGAINST A FULL-BARREL
SAFETY SYSTEM.

GOT TO MIX UP A GOOD BATCH.

Narrator: BUT THAT'S WHERE
THE SIMILARITIES END.

OKAY, WE KNOW THE OLD MOSES
BATTLE SPEED

FIRES A CANNONBALL TRAVELING
AT 1,200 FEET PER SECOND.

SO NOW THAT WE KNOW THAT,

WE CAN MATCH OUR CANNON
TO THAT SPEED.

OLD MOSES USED ONE POUND
OF BLACK POWDER

TO GET THE BALL UP TO SPEED,

BUT WE'RE GOING TO NEED TO
INCREASE THAT FOR OUR CANNON.

WHY? WELL,
THE BARREL IS SHORTER,

WHICH MEANS THAT THE BALL WON'T
HAVE AS MUCH TIME TO ACCELERATE,

SO WE'VE GOT TO GIVE IT
A LITTLE BIT MORE KICK.

TO ALLOW FOR THAT, WE'RE GOING
TO USE A BIT MORE BLACK POWDER

TO GET US UP TO THE 1,200 FEET
PER SECOND WE'RE LOOKING FOR.

Narrator: RIGHT, SO THE CANNON
IS AIMED AT THE BALL CATCHERS.

THE STEEL IS LOADED,
AND THE FUSE IS LIT.

LET'S GO.

THEN IT'S BACK TO THE BUNKER.

ALL RIGHT, FUSE IS LIT,
READY FOR THE CALIBRATION TEST.

ALL RIGHT,
LET'S SEE IF STUBBY CAN DO IT.

IT'S GOING TO BE SOON.

SO, THAT WAS THE MISFIRE

THAT SOMEHOW
SENT OUR CANNONBALL

UP AND OVER THE HUGE SAFETY BERM
AND INTO SOMEBODY'S HOUSE.

YEAH, AND WHEN WE REALIZED
THAT THAT HAD HAPPENED,

WE CALLED OFF
THE EXPERIMENT

IMMEDIATELY TO HELP OUT
ANY WAY WE COULD.

AND FIRST, THAT MEANT
LOOKING AFTER THE PEOPLE

WHOSE PROPERTY
HAD BEEN DAMAGED,

AND WE THOUGHT
IT WAS VERY IMPORTANT

THAT WE REBUILD BRIDGES WITH
THE LOCAL COMMUNITY AS A WHOLE.

AND AT THAT SAME TIME,

OUR TEAM WAS CONDUCTING
AN INVESTIGATION

TO FIGURE OUT
WHAT WENT WRONG

TO PREVENT IT FROM EVER
HAPPENING AGAIN IN THE FUTURE.

BELIEVE ME,
IT WAS AN INTENSE FEW MONTHS

FOR EVERYONE INVOLVED.

BUT ONCE WE STARTED
MAKING PROGRESS

ON ALL OF THOSE THINGS --

THE PROPERTY, THE COMMUNITY,
THE SAFETY REVIEW --

WE WANTED TO MOVE FORWARD,

AND WE STARTED THINKING
ABOUT FINISHING OFF THIS MYTH.

YEAH, AND FIRST UP

WAS TO FIND A NEW,
MORE REMOTE LOCATION.

AND THEN,
HARRY WEBB DECIDED

THAT WE COULD USE OLD MOSES

TO FIRE OUR STONE CANNON BALLS
AFTER ALL.

WHICH MEANT
THE FIRST THING UP

WAS TO FIGURE OUT WHAT TYPE
OF ROCK THESE CANNON BALLS

WERE EVEN MADE OUT OF.

GOT TO BE DIAMONDS
AROUND HERE SOMEWHERE.

Narrator:
AND FOR THAT ROCK RESEARCH,

TORY VISITED THE
CALIFORNIA ACADEMY OF SCIENCES

TO TALK TO MINERAL MAESTRO,
GEOLOGIST PETER ROOPNARINE.

WHAT WOULD HAVE BEEN
THE THREE BEST TYPES OF STONES

THAT THEY COULD HAVE USED?

WELL, I THINK SANDSTONE WOULD
HAVE BEEN A COMMON MATERIAL.

IT WAS USED FOR A LOT
OF CONSTRUCTION

IN VARIOUS PARTS
OF EUROPE.

IT'S VERY SOFT.
IT WOULD BE EASY TO WORK.

I DON'T KNOW HOW WELL
A SANDSTONE CANNONBALL

WOULD SURVIVE BEING SHOT
OUT OF A CANNON.

THEY ALSO WOULD PROBABLY
HAVE USED A LOT OF LIMESTONE.

IT'S VERY HARD BUT ALSO COMMON
AND EASY TO WORK,

AND THERE WOULD HAVE BEEN
A LOT OF EXPERIENCE

WORKING THIS KIND
OF SEDIMENTARY ROCK.

GRANITE, ON THE OTHER HAND,
IS AN IGNEOUS ROCK.

IT'S NOT AS COMMON,

BUT IT'S HIGHLY PRIZED
BECAUSE OF ITS STRENGTH.

IT'S VERY DENSE -- WOULD
PROBABLY DO A LOT OF DAMAGE.

WELL, I GUESS WE WON'T KNOW

UNTIL WE MAKE
OUR OWN CANNONBALLS

AND SEE HOW WELL THEY DO.

ALL RIGHT, NOW I HAVE
ONE QUESTION FOR YOU.

HOW MUCH KRYPTONITE
DO YOU HAVE?

THAT'S A SECRET.

Narrator: SANDSTONE, LIMESTONE,
AND GRANITE ARE THE CANDIDATES.

BUT WILL ANY HAVE
THE COMBINATION OF HARDNESS

AND COMPOSITION TO BE
AS EFFECTIVE AS METAL

AND BREAK UP ON IMPACT?

WELL, WITH EACH MYTHBUSTER
WORKING ON A DIFFERENT ROCK,

IT'S TIME FOR ALL THREE

TO PUT THEIR BOULDERS
TO THE GRINDSTONE.

GRANT DECIDES TO CARVE
HIS SANDSTONE CANNONBALL

ON THE LATHE,

WHILE KARI NEEDS
A MORE AGGRESSIVE TOOL

TO MAKE AN IMPRESSION
ON HER LIMESTONE.

CAN I SWITCH TO SANDSTONE,
PLEASE?

Narrator: BUT TORY HAS TURNED IN
THE POWER TOOLS

FOR A SUPER POWERED TOOL.

LOOK AT THIS THING.

IT'S DESIGNED
TO POLISH CONCRETE.

[ WHIRRING ]

NOW THAT'S WHAT
I'M TALKING ABOUT!

Narrator: EVEN THOUGH
THE IGNEOUS GRANITE

IS THE HARDEST ROCK
ON THE BLOCK,

THE CONCRETE GRINDER
SOON HAS IT BEAT.

I LIKE-A TO CALL THIS A-PIECE
"BALL ON THE BRICK."

WELL, I GUESS
I SHOULD MAKE ANOTHER ONE.

[ CHUCKLES ]

Narrator:
TORY'S LEADING THE WAY,

AND IT'S NOT LONG
BEFORE BOTH KARI AND GRANT

HAVE TAKEN ON
THE CONCRETE POLISHER, TOO.

YEAH, I REALLY LIKE
WORKING IN TV.

I THINK IT'S THE GLAMOUR...

THE CLOTHES...

MAKES ME FEEL REALLY PRETTY.

Narrator: AND ALTHOUGH
THE SOFTEST ROCK,

THE SANDSTONE,
IS EASIER TO CARVE,

IT HAS ITS DRAWBACKS, TOO.

THE THING IS,
BECAUSE IT'S SO SOFT,

IT WILL PROBABLY BREAK
ON IMPACT,

BUT MY QUESTION IS,

IS IT GOING TO SURVIVE
THE LAUNCH?

AFTER A LOT OF HARD WORK
AND HOURS OF GRINDING,

OUR CANNONBALLS ARE DONE
AND THEY LOOK GREAT.

WE GOT A SANDSTONE,
WE GOT A LIMESTONE,

AND WE GOT
A GRANITE CANNONBALL.

NOW ALL WE NEED TO DO IS LOAD
THEM INTO A REAL CANNON,

FIRE THEM AT A CASTLE WALL,

AND SEE HOW THEY COMPARE
TO AN IRON CANNONBALL.

Narrator:
ACCORDING TO THIS MYTH,

BY USING A MATTRESS
TO BREAK YOUR FALL,

YOU COULD HIT THE SACK
AND ESCAPE.

BUT IN REALITY, NOT SO MUCH.

HE WOULD BE EVEN MORE DEAD
THAN THE FIRST ONE.

IS THAT A MEDICAL TERM?

IT IS NOW.

HAVING ESTABLISHED THAT JUMPING
OFF A 3-STORY BUILDING,

EITHER DIRECTLY
INTO 4 1/2 FEET OF WATER

OR ONTO A MATTRESS
IN THAT WATER,

IS POTENTIALLY LETHAL,

IT BEGS THE QUESTION,
WHAT EXACTLY WOULD IT TAKE

TO JUMP SAFELY FROM THAT HEIGHT
AND INTO THAT DEPTH OF WATER?

SO WE'VE COME HERE

TO THE GEORGE F. HAINES
INTERNATIONAL SWIM CENTER

IN SANTA CLARA, CALIFORNIA,

WHERE THEY HAVE
A MAGNIFICENT POOL

AND A PLATFORM
THAT SITS PRECISELY

THREE STORIES ABOVE THAT POOL.

AND IN A LITTLE WHILE
MR. JAMES FRANKLIN HYNEMAN

IS GOING TO FIND OUT
WHAT IT WOULD TAKE

TO DIVE SAFELY FROM THIS HEIGHT.

Better him than me.

GIVEN THAT JUMPING OFF A HEIGHT
LIKE THAT

THE WRONG WAY INTO WATER
COULD SERIOUSLY HURT YOU,

I'M NOT ABOUT TO DO
ANYTHING FANCY OFF OF THAT

WITHOUT SOME TRAINING.

NOW, LUCKILY WE'VE GOT
JUST THE GUY TO DO THAT.

HE TAUGHT US HOW TO JUMP
OFF OF BUILDINGS.

HE'S WRAPPED US IN BUBBLE WRAP
AND THROWN US OFF OF BUILDINGS.

THAT WAS INTENSE.

HIS NAME IS RANDY LAMB.

HE'S A PROFESSIONAL STUNT MAN,

AND HE IS TASKED TODAY

WITH TAKING JAMIE
RIGHT TO THE EDGE

[ Chuckling ]
AND THROWING HIM OFF.

Narrator: THROWING HIM OFF
AND ENSURING THAT HIS PLUNGE

IS LESS THAN THE 4 1/2-FOOT
DEPTH OF THE MYTH.

BUT FIRST, WHAT KIND OF DEPTH

DOES THE AVERAGE DROP
FROM 35 FEET GET?

WOW!

THAT WAS REALLY COOL.
[ LAUGHS ]

I'M SCREWED.

Adam: RANDY'S JUMP CARRIED HIM
ABOUT 2/3 THE DEPTH OF THE POOL,

ABOUT 12 OR 13 FEET.

IT'S A LOT FARTHER
THAN 4 1/2 FEET,

AND I HAVE TO ADMIT
I'M REALLY CURIOUS

TO SEE WHAT KIND OF FORM
HIS SHALLOW DIVE TAKES.

Narrator: WELL, THAT'S WHAT
JAMIE IS ABOUT TO FIND OUT.

SO, RANDY,
WHAT ARE MY OPTIONS

AS FAR AS FLATTENING OUT QUICKLY
WITHOUT HURTING MYSELF?

AS YOU'RE COMING DOWN,

YOU WANT TO BE RIGHT NOW
IN A VERY VERTICAL POSITION.

JUST AS YOUR FEET
TOUCH THE WATER,

I WANT YOU TO PULL THEM
IN FRONT OF YOU.

KEEP YOUR LEGS STRAIGHT
AND PIKE RIGHT HERE, ALL RIGHT?

THIS POSITION HERE
SHOULD SCOOP YOU UP.

ALL RIGHT?

IT'S A TACTIC
THAT SHOULD SLOW JAMIE DOWN

AS HE ENTERS THE WATER

AND MAKE HIS ANGLE OF ENTRY
SHALLOWER.

AND HOW DID THAT FEEL?

IT FELT ALL RIGHT.

BUT WITH A 3-STORY DIVE

INTO THE MYTHICAL
4 1/2 FEET TO COME,

PRACTICE IS GOING
TO MAKE PERFECT.

SO, CUE THE MUSIC --

WE'RE GOING TO NEED
A TRAINING MONTAGE.

LAY BACK!
LAY BACK! NICE!

Jamie:
IF THERE'S ONE THING WE'VE
LEARNED IN ACQUIRING TECHNIQUES

TO DEAL WITH DANGEROUS
SITUATIONS LIKE THIS ONE,

IS THAT YOU NEED TO WORK
YOUR WAY UP INCREMENTALLY.

I FEEL LIKE I JUST GOT SPANKED.

YOU CAN'T JUST TAKE INSTRUCTIONS

THAT AS YOU'RE JUMPING

YOU'RE GOING THROUGH
IN YOUR HEAD, "DO THIS,

NOW I'M GOING TO DO THIS,
AND THEN I'M GOING TO DO THIS."

IT ALL HAPPENS SO FAST
IT HAS TO BE AUTOMATIC.

AND THAT'S WHAT I'M IN THE
PROCESS OF DOING RIGHT NOW,

IS BURNING THAT IN

SO THAT I DON'T EVEN
HAVE TO THINK ABOUT IT.

STAY TIGHT.
STAY TIGHT. NICE.

Narrator: AND BEFORE LONG,

JAMIE HAS GRADUATED
TO THE 15-FOOT HEIGHT.

HE SURVEYS THE DISTANCE...

ESTIMATES HIS TRAJECTORY,
AND HE JUMPS.

THAT WAS A REALLY GOOD ONE.
BARELY HEARD A SOUND.

NICE WORK, SIR.

TAKING IT DROP BY DROP,

JAMIE'S GOTTEN HIS DEPTH
TO 5 1/2 FEET,

AND HIS TECHNIQUE IS GETTING
SO GOOD THAT SOON...

Adam: THAT WAS
YOUR BEST ONE YET.

I THINK YOU SHOULD MOVE UP
AND START PRACTICING

FROM A LITTLE BIT HIGHER
TO GET COMFORTABLE UP THERE.

ALL RIGHT.

Adam: AS JAMIE PRACTICES

AND MOVES TO EVER HIGHER
DIVING PLATFORMS,

THERE'S ACTUALLY
A QUITE INTERESTING REASON

FOR WHICH HE MIGHT GET BETTER
AT DECELERATING FASTER

AS HE GOES HIGHER.

WATER RESISTS AN IMPACT

IN DIRECT PROPORTION
TO THE SPEED OF THE IMPACT.

KARI, GRANT, AND TORY
INVESTIGATED THIS

IN THEIR
"WATER vs. CONCRETE" EPISODE...

[ CHEERING ]

...AND IT DEFINITELY
APPLIES HERE.

SO, WHILE HE DID PRETTY GOOD
AT 15 FEET,

HE MIGHT BE ABLE TO ACTUALLY HIT
HIS TARGET AT 35.

THAT ONE WAS FANTASTIC.

THAT WAS AS GOOD AS
YOUR BEST JUMP FROM 15 FEET.

YEAH, WELL,
I MEAN, IF THAT ONE WAS AS GOOD

AS I GOT FROM 15 FEET,

MAYBE I'LL BE ABLE TO DO
JUST AS GOOD FROM 35.

YEAH. EXACTLY. NOTHING TO DO
BUT KEEP PRACTICING.

AND AFTER A DAY OF JUMPING IN
WITH BOTH FEET,

THAT 35-FOOT FALL WILL HAVE
TO WAIT UNTIL TOMORROW.

SO, HOW ARE YOU FEELING
AFTER ALL THAT?

OW.

SORRY ABOUT THAT.

DON'T TRY ANYTHING YOU'VE SEEN
ON THE SHOW AT HOME.

WE ARE WHAT YOU CALL...
EXPERTS.

WE'VE COME OUT
TO A QUARRY IN ANGELS CAMP

SO WE CAN TEST THE MYTH
OF THE STONE CANNONBALL.

IT WAS SAID THAT THESE WERE
NOT ONLY AS EFFECTIVE

AS IRON CANNONBALLS,
BUT THEY EXPLODED UPON IMPACT,

WHICH MEANS THEY COULDN'T
BE FIRED BACK.

HERE COMES THE CANNON.

Tory: LOOK AT OLD MOSES
READY FOR ACTION.

Tory: NOW,
SINCE WE'VE NEVER SHOT

ONE OF THESE STONE CANNONBALLS,

WE'RE GOING TO FIRE
THIS CANNON REMOTELY.

SO WHAT I'M DOING RIGHT NOW
IS I'M ROLLING OUT 500 FEET

OF WIRE SO THAT WE CAN
LAUNCH THIS THING

FROM BEHIND THIS PILE OF ROCKS
WITH AN ELECTRIC MATCH.

Narrator: AND THAT'S NOT THE
ONLY PRECAUTION THEY'RE TAKING.

Kari: FOR OUR STONE
CANNONBALL EXPERIMENT,

WE HAVE WATER BARRELS THAT ARE
STACKED 2 HIGH 3 DEEP.

BEHIND THAT A SOFT SAND BERM,

AND BEHIND THAT WE ARE WAY OUT
IN THE MIDDLE OF NOWHERE

IN A ROCK QUARRY WITH WALLS
THAT ARE 300 FEET TALL.

Narrator:
THAT'S THE SET-UP,

SO NOW TO CALIBRATE
THEIR STONE BALLS

TO THE STEEL-BALL SPEED
OF THEIR PREVIOUS TEST.

WE NEED TO TEST THE SPEED
OF THE STONE CANNONBALL,

SO WHAT DO YOU SAY WE START
WITH THE SANDSTONE?

NOW, REMEMBER, WE'RE TRYING
TO GET 1,200 FEET PER SECOND,

JUST LIKE THE STEEL BALL.

GUYS,
LET ME JUST POINT OUT,

THIS IS PROBABLY THE FIRST TIME
IN 400 YEARS

SOMEBODY HAS FIRED
A STONE CANNONBALL.

THIS IS GOING TO BE COOL.

Narrator: COOL AND TRICKY,

SINCE WITH THREE
DIFFERENT MASSES,

TO GET ALL THE BALLS TRAVELING
AT THE SAME VELOCITY,

THEY'RE GOING TO NEED A FORMULA.

SO, WE NEED TO KNOW
HOW MUCH BLACK POWDER TO USE

TO GET OUR STONE CANNONBALLS
TO HAVE THE SAME VELOCITY

AS THE STEEL BALLS.

NOW, WHEN WE PLUG IN THEIR
WEIGHTS TO A BASIC FORMULA

BASED ON KINETIC ENERGY,
THIS IS WHAT WE GET.

OUR 1.3-POUND SANDSTONE BALL

NEEDS .3 POUNDS
OF BLACK POWDER.

NOW, THE 1.4-POUND
LIMESTONE BALL

NEEDS JUST A LITTLE BIT MORE

WITH .33 POUNDS OF BLACK POWDER.

AND FINALLY OUR GRANITE BALL
WHICH IS 1.7 POUNDS

NEEDS POINT .36 POUNDS
OF BLACK POWDER,

JUST A LITTLE BIT MORE
THAN THAT.

Narrator: THAT'S THE THEORY,

BUT WILL THOSE NUMBERS WORK
IN PRACTICE?

AND WILL THE CANNONBALLS
SURVIVE THE LAUNCH?

FIRST UP TO FIND
ITS BLACK POWDER BUTTER ZONE

IS THE SANDSTONE.

OKAY, .3 OF A POUND,
WHICH IS 5 OUNCES.

Narrator: AND TO PROTECT
OLD MOSES' BARREL,

THE SANDSTONE IS PACKAGED
INSIDE A CARDBOARD CANISTER.

WE ARE LOADED.

LET'S SEE WHAT SANDSTONE
IS MADE OF.

SANDSTONE.

WHAT?

THAT'S WHAT
IT'S MADE OF.

ALL RIGHT, HERE WE GO.

THIS IS SANDSTONE
CANNONBALL SPEED TEST...

IN 3, 2, 1!

LOVE THAT ECHO
IN THE CANYON.

LET'S GO SEE WHAT IT DID.

Narrator:
CLEARLY IT ROCKED IT.

Kari: WE GOT
OUR SANDSTONE CANNONBALL

TO FIRE AT APPROXIMATELY
1,200 FEET PER SECOND.

NOW, THAT'S THE BUTTER ZONE
TO MATCH OUR STEEL CANNONBALL.

NOW WE'RE MOVING
ON TO LIMESTONE.

Narrator:
ACCORDING TO THE FORMULA,

IT SHOULD TAKE 1/3 OF A POUND
TO GET THE LIMESTONE FLYING.

LOADED.

ALL RIGHT,
THIS IS LIMESTONE SPEED TEST

IN 3, 2, 1.

WOW.

Narrator: AND NOT ONLY
DID THAT HAVE ENOUGH OOMPH

TO KNOCK THE GAUGE OVER,

IT WAS ALSO ENOUGH OOMPH

TO MATCH THE STEEL
CANNONBALL SPEED.

SO, WE'VE MANAGED TO GET
OUR LIMESTONE CANNONBALL

TO 1,200 FEET PER SECOND.

THAT MEANS LIMESTONE
IS GOOD TO GO FOR ATTACK.

Narrator:
THE FINAL ROCK TO TAKE AIM

IS THE HARDEST
AND HEAVIEST STONE CANNONBALL,

THE GRANITE, WHICH MEANS
IT NEEDS THE MOST BLACK POWDER.

CLEAR FRONT!

ALL RIGHT, HERE WE GO.

THIS IS GRANITE
CANNONBALL SPEED TEST

IN 3, 2, 1.

HEY, LOOK.
IT'S STILL INTACT.

Kari: AND WASHED.

LET'S CHECK THE HIGH SPEED.
SEE HOW FAST IT WENT.

SO, WE JUST FIRED
THE GRANITE CANNONBALL,

AND WE REACHED
1,159 FEET PER SECOND.

WE ARE IN THE RANGE
THAT WE ARE LOOKING FOR.

NOW IT'S TIME TO FIRE
INTO A CASTLE.

Narrator: SO ALL THREE BALLS ARE
UP TO SPEED AND READY TO ROCK,

JUST AS SOON AS THE MYTHBUSTERS
CAN FIND A CASTLE.

THAT IS THE MOST DISTURBING
CASTLE I'VE EVER SEEN.

Narrator:
RIGHT AFTER THE BREAK...

TIME FOR BATTLE.

Narrator: ...IT'S
THE BALLS-TO-THE-WALL FINALE

OF THE STONE CANNONBALL SAGA.

Grant: IN 3, 2, 1!

EVER SINCE WE STARTED DOING
"MYTHBUSTERS,"

WHENEVER WE'VE WANTED TO ASSESS
THE KIND OF DAMAGE

THE HUMAN BODY WOULD TAKE

UNDER THE CONDITIONS
WE WERE PUTTING IT UNDER,

WE'VE HAD TO USE
EITHER DEAD PIGS

OR BUILD RIGS THAT ASSESS THE
DAMAGE BODY PART BY BODY PART --

A FOOT, A HAND, A HEAD.

THIS THING, THE SYNDAVER,

OPENS UP WHOLE NEW VISTAS
FOR US

IN TERMS OF ASSESSING PHYSICAL
DAMAGE FROM OUR EXPERIMENTS.

I'M ONLY JUST STARTING TO GRASP
HOW AWESOME THIS IS.

WELCOME BACK.

WE HAVE BEEN ATTEMPTING
TO REPLICATE A CLIP

THAT PURPORTS TO SHOW A SAFE WAY
OF LEAPING FROM 35 FEET

INTO A 4 1/2-FOOT-DEEP
SWIMMING POOL,

AND WE'VE PRETTY MUCH BUSTED
THAT OUTRIGHT.

SO HE'D BE EVEN MORE DEAD.

WE ARE NOW INVESTIGATING WHETHER
THERE IS ANY TECHNIQUE AT ALL

THAT CAN HELP YOU
SAFELY MAKE SUCH A JUMP.

Narrator: YEP, AND YESTERDAY
JAMIE SPENT THE DAY

GETTING IN TOUCH
WITH HIS INNER AQUATIC MAMMAL.

[ GROWLS ]

Narrator:
BUT IT'S TAKEN ITS TOLL.

I TOOK A LOT OF JUMPS YESTERDAY,

AND BY THE END OF THE DAY
I WAS IN A LOT OF PAIN.

THIS MORNING, I WAS STILL
IN A LOT OF PAIN.

SO I DECIDED TO CALL
OUR ORTHOPAEDIC SURGEON

AND SEE IF THERE WAS ANYTHING
I SHOULD BE CONCERNED ABOUT,

AND HE SAID THAT,
WELL, NOT REALLY,

AS FAR AS THE TISSUE DAMAGE
OR ANYTHING LIKE THAT,

BUT THAT THAT IS A WARNING SIGN

THAT I'M TAKING
A HECK OF A LOT OF IMPACT

IN MY LOWER BACK,

AND THAT'S AN AREA I REALLY
DON'T WANT TO MESS WITH.

SO I'M HANDING IT OVER
TO OUR STUNT-GUY, RANDY.

Narrator: JAMIE'S BACK
IS TELLING HIM TO BACK OUT,

SO CUE THE STUNT MAN.

ALL RIGHT, RANDY,
IT'S ALL DOWN TO YOU, SIR.

35 FEET INTO 4 1/2.

OKAY, SURE.

HE WASN'T SUPPOSED TO JUMP
RIGHT THERE.

I DIDN'T THINK SO.

FULL MARKS FOR ENTHUSIASM.

Narrator:
FULL MARKS FOR ENTHUSIASM,

AND IT'S CLEAR
FROM THIS IMPROMPTU PLUNGE

THAT HE HAS THE TECHNIQUE DOWN.

BUT THIS TIME IT'S FOR REAL,

AND IT'S A LONG WAY FROM THE TOP
WITH A VERY SHALLOW LANDING.

WILL RANDY JUMP
AND COME UP TRUMPS?

ALL RIGHT, HERE GOES THE SCOOP
IN 3, 2, 1.

Adam: WOW.

DUDE, I THINK THAT MIGHT HAVE
BEEN SURVIVABLE.

HOLD ON,
LET'S CHECK THIS OUT.

DUDE.

HE WOULD'VE SURVIVED THAT.

I THINK YOU'RE TOTALLY RIGHT.
HE WOULD HAVE SURVIVED THAT.

HE DIPPED A FEW INCHES
BELOW THE LINE,

BUT HE'S SO DECELERATED THAT'S
JUST A BUMP ON THE BOTTOM.

THAT'S NOT AN INJURY.

RANDY'S THE MAN.
YEAH.

Narrator: RANDY'S THE MAN

BECAUSE HE'S GONE ONE UP
ON THE MYTH.

NOT ONLY DID HE TAKE THE FALL
FROM THE SAME HEIGHT

INTO THE SAME SHALLOW DEPTH,
HE MADE IT OUT INJURY FREE.

RANDY, THAT WAS BEAUTIFUL.
HOW DID IT FEEL?

Randy: IT'S NOT AS BAD AS
I THOUGHT IT WAS GOING TO BE,

BUT I CAN UNDERSTAND WHY JAMIE
IS TENDER TODAY.

[ LAUGHS ]

IT'S CERTAINLY NOT
A PAINLESS WAY TO LAND,

BUT IT SURE BEATS A SHATTERED
PELVIS AND A BROKEN SPINE.

Adam: RANDY JUST SUCCESSFULLY
JUMPED SHALLOW ENOUGH

THAT HE WOULD HAVE SURVIVED
A 35-FOOT JUMP

INTO 4 1/2-FOOT-DEEP WATER.

I HAVE TO ADMIT,

EVERYTHING THAT WE'VE TESTED
SO FAR IN THIS STORY,

I WAS NOT GIVING GOOD ODDS
FOR HIM TO BE ABLE TO DO THAT.

BUT I GUESS 30 YEARS
OF EXPERIENCE AS A STUNT MAN

COUNTS FOR SOMETHING.

SO, HOW DO YOU WANT
TO CALL THIS?

WELL, AS FAR AS THE CLIP
WE STARTED WITH GOES,

EVERYTHING
THAT THEY DESCRIBED,

EITHER JUMPING
INTO THE POOL STRAIGHT

OR JUMPING INTO THE POOL
WITH A MATTRESS ON TOP OF IT,

IS EITHER SUPER DANGEROUS
OR EVEN POTENTIALLY LETHAL.

YEAH, IT'S BUSTED.

NOT TO SAY THAT IT
COULDN'T BE DONE, THOUGH,

AT LEAST IF YOU'VE GOT DECADES
OF EXPERIENCE

AS A STUNT PERSON.

EXACTLY RIGHT, SO,

DON'T TRY THIS AT HOME.

WE DIDN'T.

MY BUTT STILL HURTS.

Narrator: CASTLES -- THEY'RE
BIG, OLD, AND MADE OF STONE,

AND WHILE YOU'LL FIND
PLENTY IN EUROPE,

IN THE STATES
THEY'RE PRETTY RARE.

SO THE MYTHBUSTERS ARE GETTING
CREATIVELY MEDIEVAL...

THIS OUGHT TO KEEP
THE SAVAGES OUT.

Narrator:
...AND MAKING THEIR OWN.

Tory: NOW, I KNOW THIS
MIGHT SEEM LIKE OVERKILL

HAVING TWO PALLETS
OF SOLID CONCRETE BRICKS,

EACH OF THE BRICKS
WEIGHING 80 POUNDS.

BUT IT'S NOT AN EXAGGERATION.

AN ACTUAL RAMPART OF A CASTLE,
WHICH IS THE BARRIER,

HAVE BEEN KNOWN TO BE 6 FEET
TO 18 FEET THICK.

WHAT WE HAVE HERE
IS AN 8-FOOT THICKNESS.

SO THIS IS GOING TO GIVE US
A GOOD REPRESENTATION

OF WHAT THAT RAMPART
OF A CASTLE WOULD BE.

Narrator:
A GREAT REPRESENTATION,

AND WITH THE STURDY CONCRETE
RAMPARTS IN PLACE,

EACH MYTHBUSTER
HAS A DIFFERENT IDEA

ON WHAT CONSTITUTES A CASTLE.

"LOWER THE DRAWBRIDGE!"

"NO, WE WILL NEVER SURRENDER."

"THEN WE WILL ATTACK!"

"DON'T WORRY, THEY ARE SHOOTING
ROCK CANNONBALLS.

I AM NOT SCARED OF THOSE."

Narrator: THAT'S THREE CASTLES
TO FACE OFF

AGAINST THREE
STONE CANNONBALLS.

BUT HOW WILL THEY KNOW
IF THE ROCK BALLS

ARE AS EFFECTIVE
AS A STEEL BALL?

WELL, WITH AN OLD MOSES
COMPARISON FOR STARTERS.

ALL RIGHT, HERE WE GO.

THIS IS CONTROL TEST
STEEL CANNONBALL

WITH ONE POUND OF BLACK POWDER

IN 3, 2, 1.

[ LAUGHTER ]

Narrator: THERE'S NO DOUBT

THAT THE METAL CANNONBALL JOLTED
THE CONCRETE,

AS IT PENETRATED TWO LAYERS
AND SHATTERED FOUR BRICKS.

Kari: THAT IS ONE EFFECTIVE
CANNONBALL.

THERE'S THE BALL.

THERE IT IS.

ALL RIGHT, LETS SEE HOW
THE STONE CANNONBALLS DO.

LET'S SEE WHY
THEY USE CANNONS.

Narrator: NOW THAT THEY'VE SEEN
WHAT STEEL CAN DO,

IT'S TIME TO TEST THIS MYTH.

WILL THE ROCKS MATCH THE METAL
AND BREAK UP ON IMPACT?

WELL, FIRST THEY'RE STARTING
WITH THE SANDSTONE.

READY, HARRY.

WITH ENOUGH BLACK POWDER
TO FIRE THE BALL

AT THE SET SPEED
OF 1,200 FEET PER SECOND...

LOADED.

...THE BALL IS IN
OLD MOSES' COURT NOW.

THIS IS SANDSTONE
VERSUS THE CASTLE

IN 3, 2, 1!

OH, THAT SOUNDED LIKE
DAMAGE TO ME.

THAT WAS A BIG BOOM.
BETTER THAN I THOUGHT.

Kari: AWESOME.

THAT DID SOME
SERIOUS DAMAGE.

AND IT SHATTERED, MEANING
THERE'S NOTHING TO SEND BACK.

Narrator: BUT EVEN THOUGH
IT PENETRATED ONE LAYER

AND DAMAGED TWO BRICKS,

THE SOFTER SANDSTONE BALL

COULDN'T MATCH THE DAMAGE
OF THE METAL BALL.

SO NEXT IT'S LIMESTONE
VERSUS KARI'S DREAM CASTLE.

THAT IS PROBABLY THE MOST
ADORABLE CASTLE I'VE EVER SEEN.

NEXT UP WE'RE GOING TO USE
THE LIMESTONE BALL

AGAINST KARI'S CASTLE.

NOW, LOOKING AT THIS BALL,

IT'S PROBABLY GOING TO DO
REALLY WELL ON DAMAGE,

AND IT'S SO POROUS --
IT'S GOT ALL THESE POCKETS --

I THINK IT'S GOING TO SHATTER,

I THINK THIS THING
IS GOING TO BE GREAT.

GOOD LUCK.

IN 3, 2, 1.

THAT SOUNDED LIKE A REALLY GOOD
DAMAGE TEST TO ME.

Narrator:
IT CERTAINLY WAS,

BECAUSE THE LIMESTONE WAS HARD
ENOUGH TO DESTROY THREE BRICKS,

CLOSER TO THE DAMAGE
THE STEEL BALL CAUSED,

AND MORE IMPORTANTLY,
IT DISINTEGRATED ON IMPACT.

Kari: LOOK AT THAT!

THAT WORKS GREAT!

Tory: THE LIMESTONE
IS INCREDIBLE!

SHATTERING.

YOU KNOW, I'M A LITTLE UPSET
THAT KARI'S CUTE CASTLE

WITH THE GIANT ORANGE PRINCESS
IS DESTROYED,

BUT I MEAN, IT WAS SO WORTH IT
WITH THESE RESULTS.

WE DESTROYED A LAYER OF BRICK,
AND THE BALL CRUMBLED.

THIS IS LOOKING SO GOOD
FOR OUR MYTH RIGHT NOW.

Narrator:
LOOKING GOOD FOR THE MYTH,

BUT THE FINAL STONE CANNONBALL
IS THE MOST ROCK SOLID OF ALL.

TIME FOR BATTLE.

Narrator:
THE GRANITE IS A LOT HARDER

THAN THE PREVIOUS ROCKS,

AND WHILE IT MAY DO SOME DAMAGE,
THE QUESTION IS,

WILL IT SHATTER
AS THE MYTH SUGGESTS?

GRANITE CANNONBALL
INTO THE CASTLE

IN 3, 2, 1.

THAT SOUNDED LIKE
SUCH A SMACK.

SOUNDS LIKE SUCCESS, MAN.

ALL RIGHT,
LET'S SEE WHAT IT DID.

DEFINITELY SCORED
IN THE DAMAGE CATEGORY.

AND LOOK WHAT'S LEFT
OF THE CANNONBALL.

I MEAN, WE DID
SOME SERIOUS DAMAGE,

ALMOST AS MUCH
AS THE STEEL CANNONBALL,

AND IT DISINTEGRATED.

NOW, I'VE SPENT HOURS
SCULPTING THIS CANNONBALL,

AND A LOT OF EFFORT
WENT INTO BUILDING THIS CASTLE.

BUT I'VE NEVER BEEN HAPPIER

SEEING TWO THINGS
I'VE BUILT DESTROYED,

ESPECIALLY WITH THESE RESULTS.

I MEAN, THE GRANITE CANNONBALL
DID THE SAME DAMAGE

AS THE STEEL CANNONBALL.

HOWEVER, THE STEEL CANNONBALL
YOU COULD HAVE SHOT BACK,

THE GRANITE CANNONBALL --
DESTROYED.

THIS ONE IS PLAUSIBLE.

WANT TO KNOW WHY WE DID
WHAT WE DID

AND WHY WE DIDN'T DO
WHAT WE DIDN'T?
