Narrator: MANUFACTURED GEMSTONES ARE TYPICALLY DESIGNED

TO IMITATE GENUINE MINED GEMSTONES.

NOT THESE -- THEY'RE MADE FROM HEATHER,

A HARDY FLOWERING PLANT WHICH GROWS WILD ACROSS SCOTLAND.

FOR CENTURIES, SCOTS USED HEATHER TO

THATCH ROOFS, STUFF MATTRESSES, AND EVEN BREW ALE.

THIS SCOTTISH COMPANY TURNS HEATHER

INTO GEMSTONE MATERIAL

FOR JEWELRY AND OTHER GIFT ITEMS.

HEATHERGEMS, AS THEY'RE CALLED,

HAVE VEINLIKE PATTERNS CREATED RANDOMLY BY THE PLANTS' STEMS.

THEREFORE, NO TWO GEMS CAN BE IDENTICAL.

WHEN THE HANDPICKED HEATHER ARRIVES AT THE FACTORY,

ITS GREEN FOLIAGE STILL CLINGS TO THE UPPER PART OF THE STEMS.

AFTER CUTTING THE PLANTS INTO LENGTHS OF ABOUT 10 INCHES,

WORKERS LOAD THEM INTO A SANDBLASTING MACHINE.

THE DRUM ROTATES FOR ABOUT HALF AN HOUR

WHILE TINY IRON PELLETS BLAST THE HEATHER INSIDE.

THE PELLETS CHIP AWAY THE BARK AND REMOVE THE FOLIAGE.

THE HEATHER COMES OUT OF THE MACHINE

AS BARE, DRIED-OUT, DELICATE WOOD.

WORKERS FORM 1 1/2-POUND BUNDLES

AND PLACE THEM IN A VACUUM-DIE CHAMBER

FOR TWO WHOLE DAYS.

FIRST, THE VACUUM DRAWS OUT

THE AIR IN THE STEMS TO CLEAR THE WAY

FOR THE DIE TO PENETRATE.

THEN, AGAIN UNDER PRESSURE, THE STEMS SLOWLY ABSORB THE DYE.

THIS VACUUM METHOD IS FAR MORE EFFECTIVE

THAN DIPPING OR SOAKING THE STEMS IN VATS OF DYE

BECAUSE THE COLOR PENETRATES DEEPLY

INTO THE HEATHER WOOD RATHER THAN

MERELY SITTING ON THE SURFACE.

THEY OPEN THE BUNDLES AND MAKE NEW ONES OF THE SAME WEIGHT,

THIS TIME COMBINING COLORS.

IT'S IMPORTANT TO COMBINE THICKER STEMS

WITH THINNER ONES TO CREATE CONTRASTING LINES

IN THE GEM PATTERN.

NEXT, THEY SOAK EACH BUNDLE

IN EPOXY RESIN FOR TWO OR THREE MINUTES,

ENSURING THE STEMS ARE WELL SATURATED.

THEN THEY PLACE THE BUNDLES ON RACKS

TO ALLOW THE EXCESS RESIN TO DRAIN OFF.

THEY LOAD FOUR BUNDLES BETWEEN

THE TOP AND BOTTOM HALVES OF A MOLD.

A PRESS THEN SLOWLY CLOSES THE MOLD,

APPLYING 88 TONS OF PRESSURE FOR ABOUT A MINUTE.

THEY CLAMP THE MOLD CLOSED AND REMOVE IT FROM THE PRESS.

THEN THEY PUT THE MOLD INTO AN OVEN FOR AN HOUR

TO CURE THE RESIN.

THEY OPEN THE MOLD AND REMOVE WHAT IS NOW

A ROCK-HARD, RESIN-BONDED BLOCK OF HEATHER WOOD.

THEY PUT THE BLOCK ON A BAND SAW AND TRIM OFF THE ROUGH EDGES.

THEY CUT SLICES BETWEEN 4/10 AND 5/10 OF AN INCH THICK,

DEPENDING ON WHAT SHAPE GEM THEY'LL BE MAKING.

AFTER GLUING EACH SLICE ONTO A PLASTIC BACKING,

A ROBOTIC CUTTING MACHINE GUIDED BY A COMPUTER

CUTS THE GEM SHAPES.

THEN WORKERS SIMPLY POP THE GEMS OFF THE PLASTIC BACKING.

THIS DOMED OVAL SHAPE IS CALLED A CABOCHON.

THE FINISHING TEAM SMOOTHES AND POLISHES EACH GEM

ON A BELT SANDER, THEN APPLIES FOUR OR FIVE COATS

OF CLEAR LACQUER.

LACQUERING DRAWS OUT THE COLORS

WHILE SEALING AND PROTECTING THE WOOD.

FINALLY, THEY GLUE EACH GEM ONTO THE JEWELRY OR GIFT ITEM.

SOMETIMES THEY DYE THE HEATHER JUST A SINGLE COLOR.

THIS STILL PRODUCES A STRIKING GEM,

BECAUSE THE DYE PENETRATES THE WOOD WITH DIFFERENT INTENSITIES,

CREATING CONTRASTING SHADES.

THE SIGNATURE FEATURE IS THE UNIQUE VEINING

PRODUCED BY THE HEATHER ENCASED WITHIN,

EACH AND EVERY GEMSTONE TRULY CAPTURING

THE NATURAL BEAUTY OF THE SCOTTISH HIGHLANDS.

Narrator: INVENTED IN THE MIDDLE OF THE 20th CENTURY,

INSTANT FILM MADE PHOTOGRAPHIC IMAGES

MATERIALIZE ALMOST MAGICALLY.

THE PICTURE APPEARED IN MINUTES.

NO MORE WAITING FOR DAYS FOR FILM TO BE PROCESSED.

TODAY IT'S A DIGITAL WORLD,

BUT INSTANT FILM IS STILL GETTING PLENTY OF EXPOSURE.

WITH INSTANT FILM, YOU CAN WATCH AN IMAGE DEVELOP

BEFORE YOUR VERY EYES --

NO FILM LAB OR DIGITAL PRINTER NECESSARY.

JUST SAY, "CHEESE," AND WAIT TO SEE WHAT DEVELOPS.

MANY DECADES AFTER ITS INVENTION,

INSTANT PHOTO DEVELOPMENT STILL SEEMS LIKE A NEAT TRICK.

MAKING THE MAGIC HAPPEN IS A MANY-LAYERED PROCESS,

ONE THAT INVOLVES MULTIPLE MATERIALS AND CHEMICALS.

PRODUCTION BEGINS WITH THE FILM NEGATIVE.

IT TAKES PLACE IN THE DARK TO PREVENT PRE-EXPOSURE.

THE TECHNICIAN DONS NIGHT-VISION GOGGLES,

ALLOWING HIM TO MONITOR PLASTIC FILM

AS IT UNWINDS INTO A COATING MACHINE.

INSIDE, VARIOUS DYES AND CHEMICALS

WILL TRANSFORM THE FILM INTO A NEGATIVE.

THEY SWITCH THE LIGHTS BACK ON BRIEFLY FOR OUR CAMERA.

THE FILM TRAVELS UP AND DOWN TOWARDS THE COATING MACHINE.

IT'S A SYSTEM THAT PREVENTS ANY SLACKENING IN THE FEED.

THE COATING IS ALSO DONE IN THE DARK,

SO THIS WORKER DEMONSTRATES THE PROCESS

FOR OUR CAMERA ON A SMALL RESEARCH MACHINE.

LIQUID PHOTO CHEMICALS AND DYES

FLOW ONTO THE SURFACE OF THE PLASTIC FILM.

HE SPREADS THE LIQUIDS ACROSS THE FILM

FOR AN EVEN APPLICATION.

THIS IS ALL DONE MECHANICALLY INSIDE THE REAL COATING MACHINE.

ONCE COATED, THE FILM WILL HEAD INTO THE DRYER.

THE VARIOUS COATINGS WILL DRY IN SEPARATE LAYERS

WITHOUT INTERMINGLING.

HERE'S A TEST TUBE LINEUP OF THE LIQUID COMPONENTS

OF THE NEGATIVE.

THE COLORFUL ONES ARE DYES,

AND THE WHITE ONES ARE OTHER CHEMICALS.

THEY APPLY BLACK BACKING TO THE NEGATIVE TO BLOCK LIGHT,

AGAIN PREVENTING PRE-EXPOSURE.

THE TRIP THROUGH THE DRYER IS 87 YARDS LONG.

HOT AIR DRIES THE CHEMICALS ON THE SURFACE OF THE FILM.

ONCE AGAIN, IT ALL HAPPENS IN THE DARK

TO PROTECT THE LIGHT-SENSITIVE FILM.

COILED UP AND PACKED INTO LIGHTTIGHT DRUMS,

THE COLOR-NEGATIVE MATERIAL IS NOW ON ITS WAY

TO A SECOND FACTORY

TO BE ASSEMBLED INTO THE INSTANT FILM PACK.

UPON ARRIVAL, THEY THREAD THE NEGATIVE ONTO A MACHINE,

ALONG WITH OTHER MATERIALS FOR THE FILM PACK.

THEY INCLUDE A PLASTIC BASE MATERIAL

CALLED THE MASK AND THE POSITIVE PAPER

THAT RECEIVES THE PHOTOGRAPHIC IMAGE FROM THE NEGATIVE.

THE VARIOUS MATERIALS ARE STEERED TOWARD ASSEMBLY STATIONS

BY A SYSTEM OF ROLLERS.

HERE'S A LINEUP OF THE VARIOUS MATERIALS TO BE ASSEMBLED.

THAT'S THE MASK ON THE FAR LEFT AND THE NEGATIVE IN THE MIDDLE.

THE NEGATIVE HEADS TOWARDS A SERIES OF HOT PRESSES.

ONE PRESS LAMINATES A PLASTIC SPACER

CALLED THE RAIL TO THE NEGATIVE.

ANOTHER LAMINATION HEAD APPLIES THE MASK

TO THE POSITIVE SHEET THAT WILL RECEIVE THE IMAGE.

ON A DIFFERENT MACHINE, EQUIPMENT FOLDS

A KIND OF FOIL POUCH AND INJECTS IT WITH FILM DEVELOPER.

HERE'S AN INSIDE LOOK AT THE POUCH.

THE BLUE LIQUID IS THE DEVELOPER.

ENCASED IN THE FOIL-LINED ENVELOPE,

IT WILL STAY FRESH UNTIL NEEDED.

BACK ON THE MAIN ASSEMBLY MACHINE,

ANOTHER HOT PRESS LAMINATES THE DEVELOPER POUCH

TO THE OTHER FILM MATERIALS.

THIS COMPLETES THE FILM SANDWICH,

AND IT HEADS INTO ANOTHER STATION

TO BE SLICED INTO PHOTO-SIZED PIECES.

THE PHOTO FRAMES RIDE A WHEEL WITH A COUNTER

THAT DIVIDES THEM INTO STACKS OF EIGHT.

MEANWHILE, ROBOT ARMS DEPOSIT A RECTANGULAR SPRING ON A BATTERY.

THEN THEY POSITION THE EIGHT PICTURES

ON THE SPRING-BATTERY ASSEMBLY,

FOLLOWED BY A LIGHT-BLOCKING COVER.

THE STACK THEN MOVES FORWARD TO BE SQUEEZED

INTO A PLASTIC CASSETTE.

A SUCTION TYPE OF DEVICE NOW PICKS UP A CARDBOARD BOX

AND TRANSFERS IT TO THE END OF THE FILM-PACK LINE.

ANOTHER DEVICE CAPTURES THE FILM PACK

AS IT COMES OFF THE LINE AND PLACES IT IN THE CARDBOARD BOX.

ONCE FOLDED CLOSED,

THE BOX OF INSTANT FILM RIDES THE CAROUSEL TO A SCALE.

A QUICK WEIGHING CONFIRMS THERE'S ENOUGH FILM IN THE BOX,

SO IT'S READY TO SHIP.

THE ASSEMBLY OF THIS INSTANT FILM PACK

HAS TAKEN ROUGHLY THREE MINUTES.

NOW THOSE INSTANT MEMORIES ARE JUST A FEW CLICKS AWAY.

Narrator: A COMMON ASSUMPTION IS THAT ALL WHITE SUGAR

IS DERIVED FROM SUGAR CANE,

BUT 30% OF THE WORLD'S WHITE-SUGAR SUPPLY

COMES FROM THE SUGAR BEET.

WHILE SUGARCANE GROWS ONLY IN TROPICAL CLIMATES,

THE HARDIER SUGAR BEET CAN BE CULTIVATED

IN COOLER REGIONS AND IN POORER SOIL.

IT TAKES ABOUT 7 BEETS TO PRODUCE

A LITTLE MORE THAN 2 POUNDS OF SUGAR.

THE BY-PRODUCTS OF PROCESSING,

MOLASSES AND BEET PULP, ARE USED FOR ANIMAL FEED.

THE PROCESSING OF SUGAR BEETS YIELDS VARIOUS GRADES OF SUGAR.

THE LOWER ONES ARE REPROCESSED TO BECOME WHITE SUGAR.

FARMERS PLANT BEET SEEDS IN THE SPRING

AND HARVEST THE MATURE CROP IN THE FALL.

MECHANICAL HARVESTERS ATTACK SIX ROWS AT A TIME.

THEY RIP THE PLANT OUT OF THE GROUND,

CHOP OFF THE LEAVES AND CROWN, LEAVING JUST THE BULBOUS ROOT.

A BEET ROOT TYPICALLY WEIGHS ABOUT 2 POUNDS.

17% TO 18% OF THAT IS SUCROSE, WHICH IS SUGAR.

A LOADER TRANSFERS THE HARVESTED BEETS INTO TRUCKS.

THE LOADER'S SIEVE REMOVES ABOUT A THIRD OF THE SOIL

ALONG THE WAY.

WHEN THE TRUCKS ARRIVE AT THE SUGAR FACTORY,

THEY UNLOAD THE BEETS, SOIL AND STONES INCLUDED,

ONTO A CONVEYER BELT,

WHICH TRANSPORTS THEM TO A WASHING STATION.

FIRST THEY HEAD INTO A REVOLVING DRUM,

WHERE, UNDER A SHOWER OF WATER,

THE BEETS RUB AGAINST EACH OTHER,

DISLODGING THE SOIL.

THE WATER FLOW FLOATS THE BEETS, WHICH THEN EXIT THE DRUM.

THE STONES STAY BEHIND,

COLLECTED IN SEPARATOR BUCKETS ALONG THE EDGE.

A SCREW CONVEYER MOVES THE BEETS TO A TRANSFER SYSTEM,

WHICH BRINGS THEM INSIDE THE FACTORY

TO BE PROCESSED INTO SUGAR.

INSIDE, SLICING MACHINES CUT THE INCOMING BEETS INTO CASSETTES,

STRIPS ABOUT THE SHAPE OF FRENCH FRIES BUT SMALLER.

THE CASSETTES TRAVEL ON A CONVEYER BELT

INTO A LARGE TANK OF HOT WATER,

WHERE THEY SOAK FOR A FEW MINUTES.

THIS GETS THEIR CELL MEMBRANES TO BEGIN OPENING,

CLEARING THE WAY FOR THE SUCROSE TO EXIT

DURING THE NEXT OPERATION,

IN WHICH THE CASSETTES ARE PUMPED TO THE BOTTOM

OF A 22-YARD-HIGH EXTRACTION TOWER.

A ROTATING SHAFT WITHIN THE TOWER

TRANSPORTS THEM SLOWLY UPWARD AGAINST THE DOWNWARD FLOW

OF HOT WATER.

THIS DRAWS OUT THE SUCROSE,

PRODUCING A SUGARY WATER CALLED RAW JUICE.

THE NEXT STEP IS TO PURIFY THIS RAW JUICE.

IN A GIANT KILN, THEY BURN LIMESTONE WITH COKE

TO PRODUCE THE CHEMICAL COMPOUND CALCIUM HYDROXIDE,

ALSO CALLED LIME MILK.

THEY ADD IT, IN SEVERAL STAGES, TO THE RAW JUICE.

MEANWHILE, THEY PRESS THE SUCROSE-STRIPPED CASSETTES

INTO PULP TO SELL AS ANIMAL FEED.

THEY ADD CARBON DIOXIDE TO THE LIME MILK-AND-JUICE MIXTURE.

THIS ABSORBS 1/3 OF THE JUICE'S IMPURITIES,

ENABLING A FILTRATION SYSTEM TO REMOVE THEM.

THE RAW JUICE EXITS AS A GOLDEN SUGAR SOLUTION

CALLED THIN JUICE.

THE THIN JUICE THEN ENTERS A 6-STEP EVAPORATION PROCESS,

WHICH REDUCES IT TO A THICK SYRUP-LIKE JUICE.

FROM THERE, THEY PUMP IT INTO A 4-PHASE CRYSTALLIZATION SYSTEM.

IN PHASE 1, THEY HEAT AND ADD SEED CRYSTALS,

TINY, IDENTICAL-SIZED SUGAR CRYSTALS

MADE SEPARATELY USING A COMPLEX COOLING AND EVAPORATING PROCESS.

AS THE WATER IN THE JUICE EVAPORATES,

ABOUT HALF OF THE SUCROSE CRYSTALLIZES,

GROWING THE SEED CRYSTALS.

THEN A CENTRIFUGE MACHINE SEPARATES THE CRYSTALS,

CALLED REFINED SUGAR, FROM THE REMAINING SYRUP.

THE SYRUP GOES THROUGH

THIS CRYSTALLIZATION-CENTRIFUGE PROCESS THREE MORE TIMES,

PRODUCING A LESSER GRADE OF SUGAR EACH TIME.

THE FACTORY DISSOLVES AND RECRYSTALLIZES

THE LOWEST TWO GRADES.

THE HIGHEST GRADES OF SUGAR GO INTO DRYERS,

ON THE WAY, PASSING THROUGH A SCREENING MACHINE

WHICH SEPARATES ANY CRYSTALS WHICH ARE TOO LARGE.

THE FACTORY DISSOLVES THESE CRYSTALS,

THEN PUTS THE SUGARY LIQUID

THROUGH THE CRYSTALLIZATION PROCESS AGAIN.

SO, IN THE END, THERE ARE TWO GRADES OF BEET SUGAR

WHICH GO INTO SILOS, WHERE THEY'RE STORED

UNTIL IT'S TIME TO PACKAGE THEM FOR SALE

AS REFINED SUGAR AND WHITE SUGAR.

Narrator: THE ELECTRIC CAR RULED THE ROAD EARLY IN THE 20th CENTURY,

AND THEN THE TECHNOLOGY WAS SURPASSED BY GAS.

TODAY THE CONCEPT IS CRUISING TOWARDS A COMEBACK,

ITS RESURGENCE FUELED BY CONCERNS

ABOUT POLLUTION FROM GAS-POWERED VEHICLES

AND BY WORRIES ABOUT OVERDEPENDENCE ON FOREIGN OIL.

THIS SASSY-LOOKING SPORTS CAR IS LEADING THE CHARGE FOR CHANGE.

JUST PLUG IT INTO ANY ELECTRICAL OUTLET,

AND AFTER A FEW HOURS, IT HAS ENOUGH JUICE

FOR A DRIVE THROUGH THE COUNTRYSIDE

OR FOR QUITE A FEW JAUNTS AROUND TOWN.

WITH NO TAILPIPE, THERE ARE NO DIRECT EMISSIONS,

AND IF THE POWER GENERATED BY THE ELECTRICAL PLANT IS CLEAN,

EVERYONE BREATHES A LITTLE EASIER.

BUT WITH A PRICE TAG IN THE 6-FIGURE RANGE,

THIS ECO-FRIENDLY ROADSTER IS A LUXURY PRODUCT.

PRODUCTION BEGINS WITH THE FIRST HALF OF THE GEAR BOX.

A WORKER BOLTS A BRASS FITTING TO THE CENTER

AND THEN ATTACHES PLASTIC TUBING TO IT.

THE TUBING WILL DELIVER LUBRICANT TO

THE TRANSMISSION'S BEARINGS.

HE INSERTS THOSE BEARINGS INTO SLOTS IN THE GEARBOX

AND PRESSES THEM INTO PLACE USING A HYDRAULIC TOOL.

HE DRIPS THREAD-LOCKING COMPOUND INTO SCREW HOLES

AND INSTALLS A DEVICE FOR LOCKING THE TRANSMISSION.

IT'S CALLED THE PARKING PAWL.

HE APPLIES MORE ADHESIVE TO SCREWS

AND THREADS THEM THROUGH THE PAWL TO THE GEARBOX.

USING A CALIBRATED TORQUE WRENCH,

HE TIGHTENS THEM TO A PRECISE SETTING.

THE TRANSMISSION IS SINGLE SPEED WITH FOUR GEARS,

WHICH THEY INSTALL IN THE OTHER HALF OF THE GEARBOX.

THESE ARE HELICAL GEARS.

THEIR TEETH ARE CUT AT AN ANGLE

FOR GRADUAL ENGAGEMENT AND SMOOTH OPERATION.

THEY'RE NOW READY FOR THE ROTOR AND THE STATOR.

BOTH ARE ELECTROMAGNETS,

AND TOGETHER THEY'LL BE THE ELECTRIC MOTOR'S DRIVING FORCE.

THEY INSERT THE ROTOR INTO THE STATOR,

WHERE THEIR TWO ELECTROMAGNETIC FIELDS

WILL INTERACT TO CREATE TORQUE,

TRANSFORMING ELECTRICAL ENERGY INTO MECHANICAL ENERGY.

THEY HOIST THE ROTOR-AND-STATOR ASSEMBLY

ONTO THE GEARBOX AND BOLT THEM TOGETHER.

THEY ATTACH CABLES FOR WIRING THE MOTOR TO

THE POWER-ELECTRONICS MODULE LATER.

IT'S A CRUCIAL PART THAT PROCESSES AND REGULATES

THE FLOW OF BATTERY POWER TO THE MOTOR.

THIS COMPLETES THE ELECTRIC-MOTOR DRIVETRAIN.

THEY LOWER THE DRIVETRAIN INTO THE BACK

OF THE PREASSEMBLED CAR BODY.

THEY POSITION THE MOTOR MOUNTS

OVER SLOTS IN THE STEEL SUBFRAME.

AND ONCE IN PLACE, THEY BOLT THE DRIVETRAIN TO THE CHASSIS.

NOW, UNDER THE CAR,

THEY PULL BACK THE REAR SUSPENSION TEMPORARILY

TO ATTACH THE DRIVE AXLE TO THE GEARBOX.

THE AXLE IS EQUIPPED WITH A RUBBER-ENCASED JOINT

THAT ALLOWS A REAR WHEEL TO REACT TO BUMPS INDEPENDENTLY,

WITHOUT REVERBERATION TO THE OTHER.

THE BATTERY IS NEXT.

SEEN HERE IN A DISPLAY MODEL OF THE POWER TRAIN,

THE METAL PACK CONTAINS MORE THAN 6,800 LITHIUM-ION CELLS

AND DELIVERS 215 KILOWATTS OF POWER,

ENOUGH JUICE TO ENABLE THIS ELECTRIC CAR TO ACCELERATE TO

60 MILES AN HOUR IN UNDER 4 SECONDS.

MACHINERY NOW LOWERS THE CAR ONTO THE BATTERY,

POSITIONING IT IN THE FRONT OF THE GEARBOX

AND JUST BEHIND THE CAR SEATS.

THEY JACK UP THE BATTERY FOR A PRECISION FIT.

THEY CONNECT WIRING FOR LOW-VOLTAGE SYSTEMS,

LIKE THE LIGHTS AND FANS.

AND NOW THE BRAINS OF THE ELECTRIC CAR --

THE POWER-ELECTRONICS MODULE.

THEY INSTALL IT ON TOP OF THE MOTOR AND BATTERY

AND WIRE IT TO BOTH.

WITH ALL THE WIRES CONNECTED,

THE MODULE IS EQUIPPED TO CONVERT DC POWER

FROM THE BATTERY TO THE AC POWER.

IT WILL THEN SUPPLY THAT CURRENT TO THE MOTOR

AS THE DRIVER STEPS ON THE ACCELERATOR.

WITH THE VACUUM SYSTEM,

THEY DRAIN AIR FROM THE BATTERY AND PUMP IN LIQUID COOLANT.

COOLANT CONTINUOUSLY FLOWS THROUGH THE BATTERY

TO MAINTAIN AN EVEN TEMPERATURE THROUGHOUT.

THE BODY PANELS ARE MADE OF DURABLE,

LIGHTWEIGHT CARBON FIBER.

AND WITH THE COMPUTER SOFTWARE UPDATED

AND THE CAR NOW COMPLETELY ASSEMBLED,

IT'S TIME FOR A TEST RUN.

AS THIS SPORTS CAR ACCELERATES, THERE'S NO THROATY ROAR.

UNLIKE A GAS-POWERED ENGINE,

THE ELECTRIC MOTOR TAKES OFF QUIETLY AND QUICKLY.
