DEPENDS ON WHO'S ASKING.
OH, PAUL,
HOW ARE YOU?
OH, LOOK AT YOU.
YOU LOOK FANTASTIC.
SO GOOD TO
E YOU.
WHEN WE ID THAT
YOU WERE COMING
TO SKATE HERE
TICKET SALES
WENT THROUGH THEOOF.
I MEAN, THEY LOVE YOU.
WELL, I'M ALWAYS HAPPY
TO HELP OUT WITH A GOOD CAUSE.
OH, LET ME TELL YOU.
THESE POOR,
LITTLE, SICK CHILDREN
THEY DAPPRECIATE IT,
THEY REALLY DO.
I THOUGHT IT WAS
FOR SAVE THE WHALES.
OH, YEAH...
WHALE CHILDREN--
THAT'S WHAT I MEANT;
LITTLE, SMALL WHALES.
WELL, UM, IF YOU DON'T MIND,
D LIKE TO GO WARM UP.
AH, PAUL...
THERE'S ONE SMALL MINOR PROBLEM.
YOU SEE, WE HAD A
LITTLE BREAKDOWN
WITH THE FREEZER
EQUIPMENT LAST NIGHT.
SO, THE ICE IS A
LITTLE SOFTER THAN...
UH... I WISH I COULDAY THAT.
BASICALLY, IT'S NONEXISTENT.
THERE IS NO ICE.
WHAT DO YOU MEAN?
THERE IS, HOWEVER
SOME LOVELY, NICE,
HARD CONCRETE.
I LIKE TO THINK OF THAT
AS ALMOST ICE.
I MEAN, THIS ISN'T
ROLL-SKATING, ALL RIGHT?
I HAVE TO HAVE ICE TO SKATE ON.
I CAN'T SKATON CONCRETE.
SURE YOU CAN.
LARRY, LARRY...
DON'T BE MR.
NEGATIVITY NOW.
LARRY, THERE'S NO SKATING.
THIS IS SHOW
SINESS
AND THE SHOW
MUST GO ON.
NOW, LOOK, PAUL, THIS IS ME.
THIS IS LARRY LARUE.
COME ON, WILL YOU TRY IT FOR ME?
DO IT FOR THOSE
BABY SEALS.
ALL RIGHT, I'LL TRY.
THE LILE SEALS;
THINK OF THEM.
OKAY.
YEAH, SURE.
THE RINK'S RIGHT OVER THERE.
YOU GO STRAIGHIN-- PERFECT,
BEAUTIFUL-- YOU WARM UP.
I GOT SOME BUSINESS
TO TAKE CARE OF.
( sighs )
CONCRETE!
JAY, I'M AT THAT CHARITY ICE
SHOW, ONLY THERE'S NO ICE.
 JAY, I CAN'T SKATE WITHOUT ICE.
WHOA!
EVERYTHI YOU'VE SEEN
ON THIS SHOW
HAS BEEN WRONG.
WRONG! WRONG!
WELL, EXCEPT F THAT BIT
ABOUT CALORIES MELTING ICE.
AN ICE-SKAR...
LOOK, MA, NO HANDS.
ANCER
DOESN'T SKATE ON ICE.
( grunts )
OH, I'M SORRY.
EXCUSE ME.
HI, GUYS.
All:
HI.
HOW'S IT GOING?
I GOT A QUESTION
FOR YOU GUYS.
WHAT DOES AN ICE-SKATER
SKATE ON?
ICE.
( buzzer buzzing )
WRONG.
ICE.
LISTEN TO ME.
YOU'RE WRONG.
ICE.
( buzzing )
ICE.
OH, WHAT DOES THAT MEAN?
THAT MEA WRONG.
THE ONG ANSWER;
THAT'S RIGHT.
ICE.
THANKS FOR PLAYING
BUT GUESS WHAT?
YOU'RE WRONG.
AN ICE-SKATER
ACTUALLY SKATES ON THIS: WATER.
NOW, YOU MAY THINK
I'M BEING A WISE GUY
BECAUSE ICE IS JUST FROZEN WATER
BUT I'M NOT.
ICE-SKATING ONLY WORKS
EN WE SKATE ON WATER.
I'M NOT KIDDING YOU ABOUT THIS.
WHEN YOU ICE-SKATE,
YOU REALLY DO SKATE ON WATER.
WHY? YOU ASK.
THE REASON
IS BECAUSE FROZEN TER
HAS A UNIQUE
PHYSICAL CHARACTERISTIC.
ICE DOES SOMETHING
THAT NO OTHER SOLID DOES
AND I CAN PROVE
WHAT I'M TALKING ABOUT
WITH THIS.
NOW, THIS IS GOING TO TAKE A FEW
MINUTES FOR IT TO DO ITS THING.
SO, I'LL COME BACK
A LITTLE LATER.
TO HELP US TAKE A LOOK
AT ICE TODAY
WE'VE ASKED PAUL WYLIE
TO JOIN US.
THERE HE IS NOW.
HEY, PAU..
HEY, GREG.
HOW'S IT GOING?
GOOD.
GOOD.
LISTEN, I GOT
A QUESTION FOR YOU.
CAN YOU TELL US A
LITTLE BIT ABOUT ICE?
WELL, SURE, YOU KNOW.
IF IT'S TOO HARD, TOO COLD
IT'S JUST CHIPPY
AND WE DON'T LIKE IT
IF IT'S TOO SOFT
IT GETS ALL MUSHY,
SO WE LIKE GOLDILOCKS ICE.
YOU KNOW,
JUST RIGHT.
JUST RIGHT, AND
DO YOU EVER SKATE
ON ANY OTHER SURFACES?
YOU MEAN, LIKE, CONCRETE?
SURE, LIKE CONCRETE.
NO, I REALLY THINK
I'LL SCK TO ICE.
HE'LL STICK TO ICE.
ICE.
IF IT'S GOOD ENOUGH
FOR PAUL WYLIE
IT'S GOOD
ENOUGH FOR ME.
WHOA!
OKAY, SO LET'S
TAKE A LOOK
AT WHAT MAKES ICE
SO UNIQUE.
WHAT CAN YOU GUYS
TELL ME ABOUT ICE?
WELL, IT'S COLD.
AND IT'S HARD.
AND IT MELTS.
IT COMES IN
DIFFERENT
FLAVORS.
YES, YES.
THIS IS ALL VERY TRUE
AND SLIGLY AMUSING,
BUT IT'S NOT REALLY
WHATAKES ICE UNIQUE.
THIS CAN IS COLD
IT JUST CAME OUT
OF THE REFRIGERATOR.
IT'S HARD
AND AT THE RIGHT TEMPETURE
IT'LL MELT AND IT ALSO COMES
IN DIFFERENT FLAVORS
SO... SO WHY CAN'T WE
SKATE ON A SODA CAN?
IT'S TOO SMALL.
( horn blows off note )
UH, WELL, YEAH
BUT EVEN IF WE COVER
THE ATING RINK IN ALUMINUM
WE STILL COULDN'T SKATE ONT.
 WHEN ALUMINUM IS HEATED
 AND MELTED, IT EXPANDS
 AND WHEN IT'S POURED
 AND ALLOWED TO COOL,
 IT TURNS INTO A SOLID
 JUST LIKE ICE.
 WHEN ALUMINUM CHANGES
 TO A SOLID, IT'LL CONTRACT--
 IT GETS SMALLER--
 BUT NEARLY ALL SUBSTANCES
 PAND WHEN HEATED
 AND CONTRACT WHECOOLED.
NOW, TT MAKES SENSE, RIGHT?
I MEAN, WHEN SOMETHING COOLS,
IT CONTRACTS.
THE MOLECULES
GET CLOS TOGETHER
AND THEREFORE IT'S DENSER--
HARDER THAN WHEN
IT WAS A LIQUID.
OW!
NOW,ET'S, UH...
LET'S TAKE A LOOK
AT WHAT WATER DOES
WHEN IT BECOMES A SOLID.
ICE.
OKAY, LET'S PRETEND THESE GALS
ARE WAR MOLECULES
AND RIGHT NOW THEY'RE
ABOUT AT ROOM TEMPERATURE.
THEY'RE LIQUID.
NOW, AT ROOM TEMPERATURE
WATER MOLECULES
ARE MOVING AROUN
WELL, SORT OF LIKE THIS
WITH ALL THIS SPACE
BETWEEN THEM, BUT...
AS WE COOL THEM,
THEIR MOVEMENT BEGINS TO SLOW
AND THEY GET
CLOSER AND CLOSER TOGETHER
SORT OF LIKE... SORT OF LIKE
THEY'RE TRYING TO KEEP WARM
AND AS THEY APPROACH FEZING,
THEY GET REALLY, REALLY DENSE
BUT WATER,
AS IT TURNS TO A SOLID
DOES SOMETHING
THAT NO OTHER SUBSTANCE DOES.
IT EXPANDS.
IN AN ICE CRYSTAL
THERE ARE EMPTY SPACES
BETWEEN THE MOLECULES
SORT OF LIKE THIS.
WATER, JUST BEFORE IT FREEZES,
IS ACTUALLY MORE DENSE THAN ICE
ON A MOLECULAR LEVEL.
NOW BECAUSE E
IS LESS DENSE THAN WATER
IT FLOATS.
HOW YOU DOING?
GREAT, HOW ARE YOU?
GOOD, THANK YOU.
UM, I'LL
HAVE A, UH...
I'LL HAVE A,
UH, WATER...
WATER AND WATER,
ON THE ROCKS, PLEASE.
SURE.
GREAT.
NOW, ICE FLOATS BECAUSE,
IN ITS SOLIDTATE
WATER IS LESS DENSE
THAN...
WATER.
THK YOU VERY MUCH.
YOU'RE WELCOME.
YES, VERY GOOD.
( aircraft engine drones )
HERE'S A, UH, IMPORTANT
FETY TIP FOR YOU.
BECAUSE WATEEXPANDS
WHEN IT FREEZES
UH, PIPES, IN AN...
IN AN UNHEATEDOUSE,
THEY COULD BURST.
EXCUSE ME.
EXPANSION IS ALSO WHATAUSES
POTHOLES IN THE STREET.
YOU SEE, WATER SEEPS DOWN
INTO A CRACK, IT FREEZES
AND EXPANDS, AND TEARS
THE PAVEMENT APART.
SO, NEEDLESS TO SAY...
OKAY, I GUESS THAT'S A CUT.
OKAY.
CUT!
NOW, YOU'RE PROBABLY
ASKING YOURSELF
WHAT DOES ANY OF THIS
HAVE TO DO WITH ICE-SKATING?
HEY, GREG.
WHAT DOES ANY OF
THIS HAVE TO DO
WITH ICE-SKATING?
PAUL, THAT'S
A VERY GOOD QUESTION.
I'M GLAD YOU ASKED IT.
NOW, TRY TO STAY WITH ME.
ICE IS LESS DENSE
AS A SOLID, RIGHT?
RIGHT.
IT EXPANDS.
AND WHEN YOU SKATE...
YOU'RE EXERTIN
PRESSURE ON THE ICE
WITH YOUR
SKATE BLADE, RIGHT?
GHT.
NOW, THE PRESSURE IS
COMPRESSING THE ICE.
IT MAKES IMORE DENSE
AND,AUL WYLIE,
WHAT IS MORE DENSE THAN ICE?
WAR?
EXACTLY.
WHEN YOU'RE
COMPRESSING THE ICE
UNDER YOUR ICE BLADE,
IT MES IT MORE DENSE
SO, IT TURNS
BACK TO WATER.
NO WAY.
YES, WAY
SO, DO YOU REMEMBER
OUR BLOCK OF ICE?
WELL, LOOK
WHAT HAPPENED.
JUST THE WEIGHT,
THE PRESSURE FROM THE WIRE
MELTED THE ICE.
NO HEAT, NO FRICTION,
NOTHINBUT PRESSURE
AND IT'S THE SAME THING
WITH AN ICE-SKATE BLADE.
Woman:
WHEN YOU'RE STANDING
ON THE SKATE
L OF YOUR
WEIGHT IS
CONCENTRATED
ON THE THIN EDGE
OF THE BLADE.
Greg:
RIGHT, AND THAT'S WHY SKATERS
LIKE THEIR BLADE NICE AND SHARP.
NOT BECAUSE IT CUTS
INTO THE ICE, BUT BECAUSE
IT CONCENTRATES THEIR WEIGHT
IN A TINY, THIN AREA.
THE PRESSURE OF THE BLADE
ON THE ICE
MAKES THE ICE CHANGE
BACK TO WAR
JUST UNDER THE BLADE.
THAT THIN FILM OF WATER IS
REALLY WHAT YOU'RE SKATING O
THE WATER LUBRICATES THE PATH
OF THE SKATE
AND THE SKATE GLIDES ALONG IT.
BUT HOW COME
YOU DON'T LEAVE
A PATH OF WATER BEHIND
YOU WHEN YOU SKATE?
THE ICE MELTS AS THE SKATE BLADE
PASSES OVER IT
AND AS SOON AS THE PRESSURE'S
OFF, IT REFREEZES.
AH!
THANK U.
SO, THAT'S WHY YOU DON'T REALLY
SKATE ON ICE.
YOU SKATE ON... WATER.
AH... YOU KNOW,
COME TO THINK OF IT
I THINK THEY OUGHT
TO CHANGE THE NAME TO, UM
WATER-SKATING... YEAH.
HEY, UH, PAUL,
D YOU... DID YOU KNOW
IF YOU WENT SOMEPLACE
REALLY, REALLY COLD
LIKE, SAY, UM, WELL,
I DON'T KNOW, E ARCTIC
THAT YOU'D PROBABLY HAVE A LOT
OF TROUBLE SKATING ON THE ICE?
BECAUSE IT'S TOO HARD, RIGHT?
RIGHT, RIGHT, THAT'S PART OF IT,
BUT IF THE ICE ITOO COLD
YOUR WEIGHT... YOUR BODY WEIGHT
WELL,  WOULDN'T BE ENOUGH
PRESSURE TO, UH, MAKE IT MELT.
REALLY?
YEAH.
HOLD IT! HOLD IT!
LET'S CUT IT, PLEASE!
( voice echoing ):
THE ICEMAN COMETH.
♪ AH-AH-AH, EE-AH. ♪
SO WHY BOTHER
KNOWING ABOUT ICE
AND HOW IT WORKS?
WELL, HERE'S SEBODY
WHO HAS A PRETTY COOL
B JUST BECAUSE
HE KNOWS ABOUT ICE.
HE'S THE ICEMAN HERE.
SO, DARYL, WHY
DON'T YOU TELL US
A LITTLE BIT ABOUT
THE ZAMBONI AND
WHAT IT DOES FOR
THE SKATING RINK.
WELL, THE ZAMBONI HAS
AN EXTREMELY SHARP BLADE ON IT
AND IT LAYS A TANK
OF HOT WATER BEHIND IT
AND MAKES IT
NICE AND SMOOTH AGAIN.
UH-HUH,
I SEE
ANDARYL, I HAVE ONE
OTHER QUESTION FOR YOU.
HAVE YOU, UH, HAVE YOU
EVER SEEN THE PLAY
 THE ICEMAN COMETH?
NO.
I THINK THERE'S A PART
IN THERE FOR YOU.
OKAY, TRY THIS.
GET SOME REALLY DRY,
FLUFFYNOW.
IT WON'T MAKE A SNOWBALL, RIGHT?
OKAY, WELL, NOW TRY UEEZING
IT TOGETHER REALLY TIGHT
AND IT MAKES A SNOWBALL
BECAUSE WHEN
YOU SQUEEZE IT TOGETHER
THE PRESSURE MELTS THE SNOW
ENOUGH, SO IT STICKS TOGETHER.
OF COURSE, IF YOU LIVE SOMEWHERE
WHERE THEY DON'T HAVE SNOW
AND, UH, I'M GOI TO GO OUT
ON A LIMB, HERE, BUT, UH...
I DON'T THINK YOU N DO THIS.
AND THAT IS WHY WE CAN'T SKATE
 ANY OTHER MATERIAL
EVEN IF IT'S HARD ANSMOOTH
AND HAS A SIMILAR MELTING POINT
TO ICE
BECAUSE  WON'T MELT
WHEN WE COMPRESS IT.
( skates scraping )
SEYOU.
BYE, GUYS.
WHOA!
( grunts )
OKAY, SEE YOU
LATER, PAUL!
THANKS FOR COMING!
OKAY, SO THAT'S IT.
THAT IS ALL.
AT IS WHY
ICE IS COOL.
OKAY, EVERYBODY,
LET'S GO, LET'S ATE.
AND A-ONE, AND A-TWO
