Delaney: MY NAME IS KEVIN DELANEY.
I'VE BEEN SHOWING OFF THE
MAGIC OF SCIENCE FOR YEARS,
FROM MUSEUMS TO TALK SHOWS.
WE'RE TAKING SCIENCE TO THE STREETS
AND COMBINING EVERYDAY ELEMENTS
IN WAYS THAT WILL BLOW YOUR MIND.
I'VE GOT A TALENTED TEAM
OF ENGINEERS AND EXPERTS,
INCLUDING THE BACKYARD SCIENTIST HIMSELF...
WAIT. THAT WAS A TWIST-OFF?
...AND OUR CINEMATOGRAPHER, DARREN,
WHO USES HIGH-TECH CAMERAS
TO REVEAL THE SCIENCE THAT SURROUNDS US
IN WAYS YOU'VE NEVER SEEN BEFORE.
THAT'S GNARLY.
THIS IS "STREET SCIENCE."
-GOT IT. -HEY, HANG ON A SECOND.
Delaney: HEY! HEY! HEY! HEY!
Delaney: THIS IS NO ORDINARY SQUIRT GUN.
IT USES PRESSURIZED AIR TO SHOOT WATER
WITH GREATER POWER AND RANGE
THAN YOUR EVERYDAY WATER PISTOL.
HANG ON A SECOND. HANG ON A SECOND!
HEY, HEY, HEY! HEY! HEY!
THIS IS FUN, BUT WHAT HAPPENS
IF WE SUPER-SIZE THESE TOYS
AND AMP UP THE WATER PRESSURE?
OUR ENGINEER, NICK
HOUSEHOLDER, HASN'T FAILED US YET.
WHOA, WHOA, WHOA. WAIT A SECOND.
WAIT A SECOND. WAIT A SECOND. NICK! NICK!
WHAT? WHAT?
IF YOU STOP THEM FROM DOING
THIS, YOU CAN BUILD A GIGANTIC ONE.
♪♪
WE'RE AT ONE OF OUR FAVORITE BREWERIES
WHERE OUR ENGINEER, NICK, IS MEETING US
WITH A SUPER-SIZED SOAKER,
AND HE DIDN'T DISAPPOINT.
♪♪
WELL, THAT'S AN IMPROVEMENT. WOW!
OUR HOMEMADE SQUIRT GUN
IS 80 TIMES MORE POWERFUL
THAN OUR SMALLER SQUIRT GUN
AND TWICE AS POWERFUL AS THE POWER WASHER
AT YOUR LOCAL CAR WASH.
POWER WASHING IS AN EVERYDAY EXAMPLE
OF DIRT BEING BLASTED OFF
THE BODY AND WHEELS OF A CAR,
SO, WHAT CAN OUR GIANT
WATER BLASTER CUT THROUGH?
WE'LL START WITH A WATERMELON.
SO, THIS GIANT WATER PISTOL
IS CAPABLE OF PUTTING OUT
3,500 P.S.I. OF WATER POWER.
IT'S THE EQUIVALENT FORCE OF A
BAT CONNECTING WITH A BASEBALL
AND HITTING IT OUT OF THE PARK.
DOES ANYBODY THINK THIS
WATERMELON IS GOING TO SURVIVE?
-I DON'T THINK SO. -IT'S GOING DOWN.
KEVIN, NICK, YOU READY TO GO?
-YES, I AM. -YOU LOOK VERY HAPPY.
I'VE GOT A GIANT WATER
GUN. HOW CAN I NOT BE HAPPY?
ALL RIGHT. GO AHEAD.
ALL RIGHT. 3, 2, 1!

[ LAUGHTER ]
-RIGHT, YES. -WHAT?!
OHH... THAT'S A PRETTY EVEN SLICE.
YEAH. THAT'S AWESOME.
THERE SHOULD BE A LAW AGAINST THIS.
[ LAUGHTER, APPLAUSE ]
♪♪
Delaney: THIS IS WHAT 3,500
POUNDS PER SQUARE INCH
OF WATER PRESSURE LOOKS LIKE.
TO COMPARE, THE WATER
PRESSURE FROM A FAUCET
IS ABOUT 30 P.S.I.,
AND THE PRESSURE FROM A
FIRE HOSE IS ABOUT 250 P.S.I.
THE WATERMELON DOESN'T STAND A CHANCE.
THAT'S ONE WAY TO MAKE A MELON BALL.
-NO, THAT'S A WATERMELON BRAIN. -[ LAUGHS ]
WE BASICALLY, LIKE, CORED IT.
LIKE... EVERYTHING INSIDE IS GONE.
NICK'S WATER CANNON WORKS
JUST LIKE SMALLER SOAKERS.
YOU MANUALLY PUMP AIR INTO A TANK OF WATER,
THEN PULL THE TRIGGER TO SHOOT
THE PRESSURIZED WATER OUT OF THE GUN,
BUT NICK'S DESIGN USES A
TANK OF PRESSURIZED GAS
TO GET BLASTING POWER
THAT WOULDN'T BE
POSSIBLE WITH HAND PUMPING.
SO, HERE'S HOW THIS WORKS.
THIS IS OUR SUPER-POWERED SQUIRT GUN.
INSIDE OF HERE IN THE HANDLE
OF A TYPICAL PRESSURE WASHER,
BUT THIS IS AN INDUSTRIAL GRADE.
IT'S MOUNTED ON THE
INSIDE OF THE SQUIRT GUN
WITH THE BARREL RUNNING
THROUGH THE BARREL OF OUR GUN.
ADDITIONALLY, WE'VE RIGGED UP
THIS COMPLEX TRIGGER SYSTEM
SO YOU SQUEEZE AND
IT FIRES, JUST LIKE THAT.
Delaney: NEXT, A
PROFESSIONAL EXERCISE BALL.
THESE THINGS ARE DESIGNED TO HOLD
UP TO 2,000 POUNDS OF
STRESS WHEN USED PROPERLY.
-3... -PROTECT THE BEER.
...2, 1!
COME ON! COME ON! COME ON!
CUT THROUGH! YEAH!
-ALL RIGHT. -WOW.
-SLICED IT RIGHT UP. -THERE IT GOES.
-YEP. -I TOLD YOU IT'D CUT THROUGH.
IT'S A SLOW, PAINFUL DEATH.
♪♪
Delaney: DARREN'S SLOW-MO
CAMERA SHOWS THAT THE PRESSURE
IS SO POWERFUL, IT
PUNCTURES THE OTHER SIDE.
♪♪
I WANT TO SEE IF OUR SUPER SQUIRT GUN
CAN PUNCTURE THESE ALUMINUM CANS,
SO I'M GONNA RIG IT UP WITH
THIS PIECE OF WOOD ON TOP,
RATCHET IT DOWN, AND VISE IT
AGAINST THESE CINDER BLOCKS,
MAKE SURE THEY CAN'T GO ANYWHERE.

[ LAUGHTER ]
-THAT WAS... THAT WAS POWERFUL. -YEAH.
-BACK SPLASH THERE. -ALL RIGHT.

Delaney: MODERN ALUMINUM CANS
ARE LESS THAN 1/10 OF A MILLIMETER THICK.
THEY'RE DESIGNED TO WITHSTAND
PRESSURE FROM THE INSIDE,
NOT THE OUTSIDE.
WHAT ABOUT A 2x4?
KEVIN KOHLER PICKS UP
THE GUN SO HE CAN AIM IT
AND TRY FOR A HORIZONTAL CUT.
THE WATER SPRAYS OUT
AT OVER 200 MILES PER HOUR.

I'M GIVING IT ALL SHE'S GOT!
[ LAUGHTER ]
-OH! -I GOT YOU. I GOT YOU.
Delaney: WOOD STOPPED
OUR SUPER-SIZED SOAKER.
THAT'S BECAUSE THIS 2X4 IS MADE OF FIR
WHICH CAN TOLERATE OVER
7,000 P.S.I. BEFORE IT SPLITS.
IT'S MUCH TOO STRONG
FOR OUR 3,500-P.S.I. BLASTER.
SO, WHAT KIND OF WATER
GUN CAN WE USE TO CHOP IT?
I THINK WE NEED MORE POWER.
YOU KNOW SOMEONE WITH A
BIGGER SQUIRT GUN THAN THIS?
-MAYBE. -SOUNDS LIKE FUN.
Delaney: SO, WE'VE REACHED THE
LIMITS OF OUR GIANT SUPER SOAKER,
BUT WE HAVE BIGGER PLANS.
WE WANT TO SEE IF UPPING THE
WATER PRESSURE CAN HELP US
CUT THROUGH MUCH HARDER OBJECTS.
NICK MAY HAVE A LINE ON A WATER
GUN WITH A LOT MORE POWER.
♪♪
WHAT'S COOLER THAN A GIANT SQUIRT GUN?
HOW ABOUT A GIANT WATER BUCKET?
THIS ONE DUMPS 65 GALLONS
OF WATER EVERY MINUTE
ON ANYONE WHO WANTS TO COOL OFF.
IT'S A HOT DAY, SO IT SHOULD BE
EASY TO RECRUIT SOME VOLUNTEERS.
YOU GUYS WANT TO GIVE US A HAND?
-SURE. -ALL RIGHT. COME ON OVER.
-YEAH. JOIN US. -SOUNDS GOOD.
ALL RIGHT, EVERYBODY. WE'RE LOOKING AT
THE ABSORBENCY OF DIFFERENT MATERIALS,
SO WE HAVE ALL THIS STUFF BACK HERE
THAT NICK AND ANNE-LISE HAVE PUT TOGETHER.
WE HAVE SPONGES, WE HAVE
TOWELS, AND WE HAVE DIAPERS.
THESE MATERIALS ARE THE ONLY THING BETWEEN
OUR VOLUNTEERS AND A GIANT DUMP OF H2O.
SO, WE'RE GONNA TURN ON THE BUCKET,
AND ONCE IT TIPS OVER,
WE'RE GONNA SEE EXACTLY HOW ABSORBENT
EACH ONE OF THESE MATERIALS ARE.
WHAT DO YOU THINK? -I'D SAY
THE DIAPERS WOULD SOAK UP THE MOST WATER.
- I WAS THINKING TOWELS.
- SHE'S THINKING TOWELS.
♪♪
Delaney: IN ORDER TO DUMP WATER
ONTO THE SPONGES, TOWELS, AND DIAPERS,
NICK'S TEAM BUILT THIS CONTRAPTION.
WATER WILL POUR INTO IT, AND
ANY WATER THAT'S NOT ABSORBED
WILL FLOW THROUGH THIS SIEVE.
OH, AND HERE'S THE CATCH...
THE VOLUNTEERS WILL STAND UNDER THE SIEVE.
Dyk: YOU GUYS ARE LIKE THE CRANE HAMSTERS,
RUNNING ON A WHEEL TO
GET SOMETHING TO GO UP.
- I THINK THAT'S GOOD.
- DRENCHING DEVICE ENABLED.
Delaney: FIRST, WE WANT TO SEE
WHAT A 65-GALLON WATER DUMP
LOOKS LIKE WITHOUT ANY
ABSORBENT MATERIAL IN THE SIEVE.
WE HAVE A VOLUNTEER
READY TO GET A LITTLE WET.
ALL RIGHT, NICK. GO AHEAD.

NOW WE'RE GONNA FIND OUT
WHAT CAN STOP THIS FROM POURING DOWN.
Householder: IF ANYTHING.
-SPONGES? -LET'S TRY IT.
Delaney: WE'VE GOT 2,000 SPONGES.
-YOU READY? -READY.
GO FOR IT.
Delaney: THIS COULD WORK. SPONGES
HAVE HOLES BETWEEN THE FIBERS
THAT SOAK UP THE LIQUID.
♪♪
-AAH! -WELL...
Emig: I FEEL LIKE THAT
WASN'T AS MUCH WATER.
I FEEL LIKE... YEAH.
IT SIGNIFICANTLY CUTS DOWN
ON THE AMOUNT OF WATER.
ARE THE SPONGES WORKING, MATT? -NOT REALLY!
OH, BUMMER.

Delaney: I GUESS THESE SPONGES
ARE BETTER FOR SMALLER JOBS.

SPONGE DIDN'T DO VERY WELL.
IT FELT LIKE IT WAS COMING
STRAIGHT FROM THE THING.
ALL RIGHT, GUYS. TOWELS ARE UP.
-OKAY, COOL. -YOU READY?
THAT'S A LOT OF TOWELS IN THERE, GUYS.
I THINK THIS ONE WILL BE
BETTER THAN THE SPONGES.
-I THINK SO, TOO. -HERE IT COMES.
Emig: OH, LET'S SEE.
♪♪
- NOT TOO BAD. NOT TOO BAD.
- WE GOT A LITTLE WATER.
♪♪
Delaney: COTTON TOWELS ARE A
DEFINITE IMPROVEMENT OVER SPONGES.
ON A MOLECULAR LEVEL, COTTON CELLULOSE
ATTRACTS WATER MOLECULES
ALLOWING IT TO HOLD
MORE THAN 20 TIMES ITS WEIGHT IN WATER,
AND THE LOOPS IN COTTON TOWELS
INCREASE THE SURFACE
AREA FOR EXTRA ABSORBENCY.
ALL RIGHT, EVERYBODY, RAISE YOUR HAND
IF YOU'VE EVER BEEN A BABY BEFORE.
EXCELLENT.
WHO ORIGINALLY SAID, "DIAPERS"?
YOU WANT TO GO UNDER THERE? -YEAH.
I'LL PROVE EVERYONE ELSE WRONG.
GO FOR IT, MAN.
YOU'RE BETTING ON THIS ONE, RIGHT?
YEAH.
-ARE YOU READY? -OH, YEAH. LET'S DO IT.

-BUTTON IS PRESSED. -HERE IT COMES, CHRIS.
♪♪
-WHOA, BARELY EVEN A DROP. -NOTHING.
[ APPLAUSE ]
GO, DIAPERS.
Delaney: DIAPERS ARE THE CLEAR WINNER,
BARELY LETTING A DROP THROUGH.
THE BOTTOM LINE... DIAPERS
HAVE A MATERIAL IN THEM
CALLED SODIUM POLYACRYLATE
WHICH CAN ABSORB UP TO 200
TO 300 TIMES ITS WEIGHT IN WATER,
A GOOD THING IF YOU'RE A BABY.
THANK YOU FOR PUTTING
YOUR BODY ON THE LINE.
I TRUSTED THE DIAPERS.
GOOD PIECE OF ADVICE.

WE'RE MOVING ON TO A CAR
WASH WHERE WE'RE GOING TO TAKE
OUR SUPER SOAKER GAME TO THE NEXT LEVEL.
-WHAT'S UP, MAN? -HOW YOU DOING, MAN?
HOW'S IT GOING, GUYS? WHAT'S UP?
HOW OFTEN DO YOU USE ONE OF THOSE
PRESSURE WASHERS TO WASH YOUR CAR?
LIKE ONCE OR TWICE A MONTH.
OUR ENGINEER HAS ANOTHER ONE
THAT'S A LITTLE BIT STRONGER THAN THAT ONE.
YOU INTERESTED IN SEEING IT? -SURE.
ALL RIGHT. COME ON.
Householder: HERE COMES
THE PRESSURE WASHER.
IT'S NOT JUST A LITTLE BIT BIGGER.
IT'S 10 TIMES MORE POWERFUL
THAN THE OTHER ONE.
THIS IS FRANK. THIS IS
FRANK'S HYDRO BLASTER.
IT'S A HIGH-PRESSURE WASHER
USED TO STRIP RUST, GRIME, AND PAINT.
IT FIRES AT 40,000 P.S.I.
THAT'S MORE THAN 10 TIMES MORE POWERFUL
THAN NICK'S SUPER-SIZED WATER GUN.
WE'RE GONNA FIRE IT AT THINGS
MUCH HARDER THAN A WATERMELON
LIKE WOOD, CONCRETE, A STEEL-BELTED TIRE,
AND EVEN A BOWLING BALL.
OUR SUPER SOAKER
COULDN'T DO MUCH TO THIS 2x4
OTHER THAN GET IT WET,
SO NICK ATTEMPTS TO TAKE AIM WITH THIS.
DON'T FALL OVER.

Delaney: ENTER THE HYDRO BLASTER.
WE'RE FIRING UP A
HIGH-POWERED PRESSURE WASHER

Delaney: A BOWLING BALL IS MADE
WITH A POLYESTER-RESIN CORE
SEALED WITH A HARD URETHANE FINISH.
ITS HARDNESS IS EQUIVALENT
TO A CONSTRUCTION HARD HAT.
- HERE YOU GO, KEVIN.
- THAT WORKED PRETTY WELL.
IF YOU EVER WANTED TO
KNOW WHAT WAS ON THE INSIDE
OF A BOWLING BALL, NOW YOU KNOW.
I HAVE. HOW ABOUT THAT?
Delaney: FRANK MANAGES TO
CUT THIS BOWLING BALL IN HALF,
BUT WHAT ABOUT SOMETHING EVEN HARDER?
NOW OUR HYDRO BLASTER WILL
TAKE ON A STEEL-BELTED TIRE.
FRANK WILL HAVE TO CUT
THROUGH A LAYER OF STEEL,
SUPER STRONG MICROFIBERS,
AND AN INLAY OF RUBBER.

GO ALL THE WAY THROUGH?
THE COMPRESSIVE STRENGTH
OF THIS CONCRETE BLOCK
CAN BE AS HIGH AS 5,000 P.S.I.,
BUT IT'S NO MATCH FOR THE HYDRO BLASTER.
IT'S TURNED THIS BLOCK INTO ROCKS.

SO, I THINK WHAT SURPRISED ME
MOST ABOUT THE HYDRO BLASTER
IS THAT IT WAS SO PRECISE.
I WAS REALLY SURPRISED AT JUST
HOW ACCURATELY IT COULD CUT.
I WAS REALLY BLOWN AWAY
BY THIS HYDRO BLASTER.
I HAD NO IDEA THAT WATER
WAS ABLE TO CUT THROUGH
SUCH DENSE MATERIALS
LIKE A TIRE OR CONCRETE.
YOU SURE YOU DON'T WANT ONE?
IT'S THIS OR A CHAINSAW, MAN.
I HAVEN'T DECIDED. -ALL RIGHT.

WITH A CHEMICAL USED AS A WOUND CLEANER.
JOHN, THERE'S A LITTLE
BIT OF GLYCERIN FOR YOU.
-THANK YOU. -AND SARAH, HERE.

Delaney: THE PURPLE STUFF IS AN ANTISEPTIC
CALLED POTASSIUM PERMANGANATE.
WHEN MIXED WITH GLYCERIN,
IT ACTS AS AN OXIDIZER

NEXT, I'M ON THE STREET
WITH THIS PLASTIC BAG
AND A CHALLENGE.

ONE OF YOU CAN PROBABLY INFLATE THIS BAG
COMPLETELY WITH ONE BREATH OF AIR.
DO YOU THINK YOU CAN DO THAT? -YES, SIR.
HERE... YOU WANT TO HOLD ONE END,
AND HOLD IT UP FOR HIM.
OH.

Delaney: WHEN I BLOW INTO THE BAG,
I CREATE AN AREA OF LOW PRESSURE
RIGHT AT THE OPENING OF THE BAG.
HIGHER-PRESSURE AIR
AROUND ME IN THE ATMOSPHERE
RUSHES INTO THE BAG TO EQUALIZE
THINGS AND FILLS UP THE BAG.
THE FASTER THE STREAM OF AIR MOVES,
THE LOWER THE PRESSURE DROPS AROUND IT.
THE SECRET IS TO BLOW INTO
THE BAG FROM A FEW INCHES AWAY
AND LET AIR TURBULENCE
DO THE REST OF THE WORK.

Delaney: THE CHAINSAW
TOOK LESS THAN HALF THE TIME
TO CUT THE LOG COMPARED

APPLIED TO A VERY SMALL AREA
