HE'S A SCIENCE TEACHER AND PART OF THE NATIONAL WEEK OF MAKING STARTING JUNE 16th. PLEASE WELCOME "SCIENCE BOB" PFLUGFELDER. >> THANKS FOR SCIENCE! >> Jimmy: DID YOU MEET JOHNNY DEPP? >> I DID, VERY NICE GUY, VERY FRIENDLY. >> Jimmy: WHAT ARE WE GOING TO DO HERE? I LIKE SHOWING HOW SCIENCE IS USED IN EVERYDAY THINGS. ANYONE THAT HAS A SMALL CHILD THAT USES DIAPERS? >> Jimmy: I HAVE A SMALL CHILD THAT USES DIAPERS AND OCCASIONALLY I WEAR ONE MYSELF. >> THEY NEED TO DO A SHOTOUT TO POLYMER SCIENTISTS. POLYMERS ARE LONG CHAINS OF MOLECULES. HERE'S A DIAPER. THERE ARE SURPRISES INSIDE OF DIAPERS. >> Jimmy: YES, THERE'S ALWAYS A SURPRISE. [ LAUGHTER ] >> TEAR THIS OPEN AND THEN SHAKE IT OVER THE TABLE. >> Jimmy: OKAY. >> YOU SEE THIS POWDER? >> Jimmy: YEAH. COCAINE? >> NO, THAT'S A POLYMER. >> Jimmy: OH. >> IT HAS A VERY SPECIAL JOB. WE HAVE A VERY LARGE AMOUNT OF WATER. THEN THIS IS DIAPER POLYMER. WE'LL SHOW YOU HOW THAT POLYMER WORKS. TAKE THIS WATER, DUMP IT INTO THE POLYMER. NICE BIG FELL SWOOP THERE TO STIR IT UP. >> Jimmy: DID YOU EMPTY LIKE 100 DIAPERS TO GET THAT? >> THAT'S A LOT OF WORK. >> Jimmy: ALL RIGHT. I SHOULD JUST DO IT? >> DUMP THAT IN THERE, ONE QUICK DUMP. >> Jimmy: THIS IS JUST WATER? >> YEAH, THERE IT GOES. >> Jimmy: WHOLE THING? >> YEP, WHOLE THING. THAT GOES IN THERE. >> Jimmy: WOW, THIS KID HAD A LOT TO DRINK. >> THEN WE GIVE IT, I DON'T KNOW, FOUR SECONDS. >> Jimmy: THAT'S WHAT'S IN DIAPERS? >> THAT'S WHAT'S IN DIAPERS. [ CHEERS AND APPLAUSE ] >> Jimmy: CAN WE MAKE IT COME OUT? WOW, LOOK AT THAT. CAN I TOUCH IT? OR IS IT POISONOUS? >> NO, NO, DIG IN. >> Jimmy: WOW, IT'S WARM TOO. OH, IT'S KIND OF FUN TO PLAY WITH. >> IT IS. >> Jimmy: CAN YOU DO THIS AFTER THE DIAPER HAS BEEN USED? I WOULDN'T WANT TO WASTE ANY. >> THAT WOULD BE GROSS. >> Jimmy: ALL RIGHT. >> WE'RE NOT DONE WITH POLYMER SCIENCE. THERE'S ANOTHER KIND OF POLYMER, IT'S THE SAME BUT THE MOLECULES AR LITTLE DIFFERENT. YOU WOULDN'T WANT TO USE THESE IN TYPERS. WE'LL SHOW YOU WHY IN JUST A SECOND. WE'LL DO THE SAME THING. POUR THAT INTO THAT. WE STIR IT UP. THERE IT GOES. >> Jimmy: IS THAT SUND COMING FROM THIS? OR THAT IS COMING FROM THE BAND? [ LAUGHTER ] >> THIS HAS A LITTLE BIT OF A DIFFERENT REACTION. THAT WE DIDN'T INCREASE THE VOLUME. WATCH THIS. IF WE START TO JUST POUR SOME OF THIS POWDER THAT'S CREATED OUT OF THIS -- YOU'LL SEE THAT THIS EXPANDS. THIS IS AN EXPANDING POLYMER. IT WILL END UP TAKING WAY MORE SPACE -- >> Jimmy: THERE'S MORE, YEAH. [ CHEERS AND APPLAUSE ] >> KEEP GOING, KEEP GOING. YEAH. >> Jimmy: CAN I MAKE A SNOWBALL OUT OF THIS? YOU CAN'T MAKE A SNOWBALL OUT OF THIS. BUT I CAN MAKE A GOOPBALL OUT OF THIS. LOOK OUT, GUILLERMO! [ DRUMROLL ] [ CHEERS AND APPLAUSE ] >> Jimmy: SORRY ABOUT THAT. >> POLYMERS ARE FUN. ALL RIGHT. >> Jimmy: WHAT ELSE? >> SHOULD WE DO A LITTLE FIRE? >> Jimmy: YEAH, LET'S DEFINITELY BURN THINGS, YEAH. [ CHEERS AND APPLAUSE ] >> THIS IS A LITTLE SOMETHING THAT MY YOUTUBE FOLKS WANTED ME TO EXPERIMENT A LITTLE BIT WITH. SO THIS IS JUST GOOD OLD-FASHIONED BLOW TORCH. GOT TWO STAGES TO IT. A HALF SQUEEZE PUTS THE GAS OUT. THEN THAT LIGHTS IT. >> Jimmy: OKAY. >> ALL RIGHT? THERE'S SOMETHING IN SCIENCE CALLS A DEFLAGRATION WAVE. A DETONATION ALSO WHEN YOU TRIGGER DINE NIGHT. A DEFLAGRATION IS ALL THE FIRE THAT COMES OUT OF IT THAT SUPERHEROES RUN AWAY FROM. THIS IS FIRE, DON'T DO THIS AT HOME. ON THE OTHER HAND, IF YOU WANT TO TRY IT, IT'S SUPER EASY. [ LAUGHTER ] >> Jimmy: OKAY. >> GO AHEAD AND PUT THE END OF THAT IN THERE. >> Jimmy: OKAY. >> ALL RIGHT. TURN THE GAS ON. BUT -- HALFWAY. NOW WE'RE FILLING IN WITH PROPANE. WE'RE GOING TO SEE IF WE CAN CREATE A DEFLAGRATION WAVE. TRIGGER IT OFF. SQUEEZE IT ALL THE WAY. >> Jimmy: WE'LL GET THE FLAME IN THERE? YEAH, YEAH. YOU SEE THAT? >> Jimmy: OH! >> THIS IS A SELF-PROPAGATING WAVE THAT SHOOTS DOWN -- >> Jimmy: IT'S LIKE "STAR WARS." [ CHEERS AND APPLAUSE ] YOU COULD KILL BATMAN WITH SLSLIDE SOMETHING LIKE THIS. >> THAT'S KIND OF COOL. I'M A MAKER SO I DECIDED TO SEE IF WE COULD RATHEMP IT UP A LIT BIT. I MADE A LITTLE SHOULD GO FOR YOU. COME ON OVER HERE. WATCH YOUR HEAD THERE. [ CHEERS AND APPLAUSE ] YOU COME OVER HERE. >> Jimmy: WHERE DID THAT COME FROM? >> SO I FIGURED, YOU KNOW, LET'S BEND THE TUBES A LITTLE BUSINESS. THIS IS A DNA MOLECULE. YOU KNOW WHAT DNA STANDS FOR IN. >> Jimmy: DADDY NEEDS ALCOHOL? >> DEOXY RIB BOW NEW CLAYIC ACID. YOU HAVE A SMART CROWD. [ CHEERS AND APPLAUSE ] >> Jimmy: WHERE DID THEY COME FROM? >> ALL RIGHT. >> Jimmy: WE HAVE A DUMB HOST WHAT IS WE HAVE. >> WE'RE GOING TO SQUEEZE BODY THOSE TRIGGERS HALFWAY. ALL RIGHT, WE'RE GOING TO DO A QUICK COUNTDOWN. WE'VE ALSO ADDED SOME MUZZLES TO THE END WHERE EXTRA PROPAIN CAN GATHER. HERE WE GO. THREE, TWO, ONE -- >> Jimmy: WHOA! [ CHEERS AND APPLAUSE ] WHAT IF WE PUT SOME OF THAT SNOW POWDER IN HERE? WILL WE HAVE A REAL CRAZY EXPLOSION? I'LL KILL YOU, BATMAN! >> THE NATIONAL WEEK OF MAKING, AN ORGANIZATION THE NATION OF MAKERS, JUNE 16th TO 22nd, WE ARE ENCOURAGING ALL MAKERS OUT THERE, WHETHER A WOODWORKER, MAKE STUFF WITH GLUE GUNS AND CARDBOARD -- >> Jimmy: YOU MAKE METHAMPHETAMINE, FOR INSTANCE? >> #NATIONOFMAKERS, ADAM SAVAGE FROM MYTH BUSTERS, WE'LL CHECK IT OUT AND HAVE A MAKER COMMUNITY. >> Jimmy: THERE WILL BE SEX? >> I DON'T THINK SO. >> Jimmy: ALL RIGHT. WHAT ARE WE GOING TO DO HERE? >> MAFBLS DOWN FOR A SECOND HERE. WE HAVE OUR OLD FRIEND. DO YOU REMEMBER? >> Jimmy: LIQUID NITROGEN. >> 320 DEGREES BELOW FAHRENHEIT, 198 CELSIUS. >> Jimmy: DO YOU WANT A SHOT, GUILLERMO? >> REMEMBER, IF YOU POUR THIS ON THE FLOOR, YOU GET THIS LIGHT AND FROST EFFECT. YOU CAN WATCH IT DANCE ACROSS THE FLOOR. >> Jimmy: CAN I DO THAT? >> GO AHEAD, SURE. SEE THAT? IT'S SO COLD IT DANCES ACROSS. >> Jimmy: YES. >> WE'RE GOING TO USE THIS TO CREATE PROJECTILES. >> GOOD. >> HERE'S WHAT I'VE DONE. TAKEN YOUR TYPICAL FIVE-GALLON WATER BOTTLE. AND WE'VE HACK THE IT AND ADDED A SIX-INCH BARREL. >> Jimmy: YEAH, BUT WHY? WHY WOULD YOU DO THIS? >> BECAUSE WE CAN. WE'RE PUTTING 450 PING-PONG BALLS IN THERE. AND THEN THE BACK WE HAVE A CHAMBER FOR SOME HOT WATER. HERE'S WHAT'S GOING TO HAPPEN. LIQUID NITROGEN GOES IN HERE, STEP ONE. STEP TWO, HOT WATER GOES IN HERE. THERE'S A VALVE THAT KEEPS THEM FROM MIXING. STEP THREE, A CAP HERE. STEP FOUR, A CAP HERE. >> Jimmy: ARE YOU LISTENING TO THIS? >> THEN ON MY CUE PULL THIS LEVER. THAT WILL MIX OUR LIQUID NIT NITROGEN, OUR HOT WATER. IT HAS AN EXPANSION RATIO OF ONE TO 700. IN OTHER WORDS WE'RE GOING TO CREATE PRESSURE. IF ALL GOES WELL THERE'S A MEMBRANE IN HERE WHICH SHOULD SEND PING-PONG BALLS FLYING. >> Jimmy: LET'S DO THIS. >> ALL RIGHT, HERE WE GO. [ CHEERS AND APPLAUSE ] ALL RIGHT, STEP ONE. GRAB ONE OF YOUR LIQUID NITROGENS. >> Jimmy: GOT TO GET THE LIQUID NITROGEN, HERE IT IS. >> POUR THAT CAREFULLY INTO THE RED FUNNEL. >> Jimmy: THE WHOLE THING? >> YEAH. THAT'S GOING TO POUR IN THERE, OF COURSE IT'S STILL LIQUID, YOU CAN SEE SOME OF THE VAPOR AROUND IT. THAT'S MOISTURE THAT'S IN THE AREA VAPORIZING. >> YEAH? >> THERE WE GO. HOW'S IT GOING, IS IT BUBBLING A LITTLE BIT? IT TENDS TO DO THAT. >> Jimmy: OKAY. >> ALL RIGHT. >> Jimmy: THAT'S IT. >> ONCE YOU'VE GOT THAT IN THERE, ALL RIGHT, YOU HAVE ANOTHER FLASK THERE, IT'S GOT THE HOT WATER IN IT. >> Jimmy: GOT IT. >> ALL RIGHT THAT GOES IN THE BACK? >> Jimmy: GUILLERMO, YOU'RE NOT HELPING AT ALL. >> POUR THAT INTO THE CHAMBER. YOU'RE GOING TO FILL THAT UP TO THE RED LIN. >> Jimmy: THIS LOOKS LIKE CHILDREN'S TYLENOL. >> ALL RIGHT. YOU GOT A LITTLE CAP TOWARDS THE BACK THERE. >> Jimmy: OKAY. >> RIGHT UP TO THE RED LINE. A LITTLE CAP IN THE BACK. GO AHEAD, SCREW THAT ON. >> Jimmy: OKAY. >> ALL RIGHT, PULL THE FUNNEL OUT. >> Jimmy: WHAT? >> Guillermo: PULL IT OUT? >> YEAH, YOU GOT IT, GUILLERMO. THAT'S GOOD. >> Jimmy: CAN YOU PROMISE ME WE'RE NOT GOING TO KILL ANN WILSON? >> ALL RIGHT, LITTLE CAP GOES ON THE TANK. >> Guillermo: HOLD ON, HOLD ON. WAIT, HOLD ON. >> YOU GOT THAT? >> Jimmy: ALL RIGHT. >> YOU GOT IT, GUILLERMO? >> Guillermo: GOT IT. >> ALL RIGHT. HAND OVER HAND, ARE YOU READY? PING-PONG CANNON IN THREE, TWO, ONE -- [ CHEERS AND APPLAUSE ] >> Jimmy: WOW. >> Guillermo: WOW! >> Jimmy: HOLY COW. LET'S LOOK AT THAT AGAIN. >> Guillermo: THIS IS SO COOL. >> Jimmy: THAT WAS CRAZY.
