>>Jimmy: HI THERE. WE’RE BACK. HARRISON FORD IS HERE. THIS GUY MAY NOT BE CAPTAIN OF THE MILLENNIUM FALCON BUT OUR NEXT GUEST COULD BUILD A LIGHTSABER WITH HIS EYES CLOSED. HE’S AN ELEMENTARY SCHOOL TEACHER FROM BOSTON AND HE’S HERE TO DELIGHT US ONCE AGAIN. PLEASE WELCOME SCIENCE BOB PFLUGFELDER. [ CHEERS AND APPLAUSE ] HOW ARE YOU? HARRISON FORD. WELCOME. THANK YOU FOR COMING.>>WOW. VERY EXCITING.>>Jimmy: SO WHAT ARE WE GOING TO DO? WHAT HAVE YOU BROUGHT FOR US?>>YEAH. I THOUGHT WE’D START WITH A LITTLE BIT OF CHEMISTRY. YOU GUYS LIKE CHEMISTRY? [ CHEERS AND APPLAUSE ]>>YES.>>GET YOUR GOGGLES ON.>>THANK YOU FOR REMINDING US.>>CHEMISTRY IS SORT OF AS CLOSE AS YOU COME TO MAGIC. RIGHT? SOMETIMES IT APPEARS TO BE MAGIC. WE’VE GOT A COUPLE OF BEAKERS HERE THAT ARE FILLED WITH VARIOUS CHEMICALS. THIS FIRST ONE HERE IS ACTUALLY FILLED WITH A LITTLE BIT OF WATER, A LITTLE BIT OF SULFURIC ACID AND A LITTLE POTASSIUM IODIDE. HARRISON, IF YOU WANT YOU CAN TAKE THAT LITTLE ONE. THAT’S GOT SOME STARCH IN IT. AND YOU CAN POUR IT INTO — >>Jimmy: THAT’S ALSO SULFURIC ACID.>>JUST POUR THAT RIGHT IN THERE. AND YOU’LL SEE WE GET NOT MUCH GOING ON THERE. RIGHT?>>RIGHT.>>A LITTLE BIT OF A BLUE COLOR BECAUSE THIS IS ACTUALLY A REACTION THAT REQUIRES ELECTRICITY. A LOT OF PEOPLE DON’T KNOW. YOU CAN TAKE THOSE BATTERIES AND DROP THEM IN THERE.>>Jimmy: OKAY. BOTH OF THEM?>>YEAH.>>Jimmy: WHY DON’T WE DROP ONE EACH? HOW DOES THAT SOUND?>>OKAY. TEAMWORK.>>Jimmy: THERE’S ONE. AND TWO.>>TERRIFIC. AND SO NOW WE CAN TURN THIS AND YOU CAN SEE THE BUBBLES THAT ARE COMING FROM IT. LET’S SEE IF I CAN TURN IT AROUND. SO WHAT WE’RE ACTUALLY DOING IS WE’RE OXIDIZING THIS CHEMICAL. AND THAT IS CREATING THE BLUE.>>Jimmy: YOU EVER DO THAT THING WHERE YOU PUT YOUR TONGUE ON THE 9-VOLT BATTERIES?>>OH, YEAH. THAT’S GREAT.>>Jimmy: WHY DON’T WE DO THAT?>>IT IS QUITE A THRILL. [ LAUGHTER ] ALL RIGHT. SO NOW WE’VE GOT — IF YOU HAVEN’T TRIED, IT GIVE IT A TRY. NOW WE’VE GOT THIS NICE BLUE. THAT’S KIND OF COOL. NOW, THIS IS AN ANTIOXIDANT. THAT’S ACTUALLY VITAMIN C. >>THAT’S WHERE BLUE COMES FROM.>>YES. [ LAUGHTER ]>>Jimmy: THAT’S WHERE THE COLOR BLUE WAS BORN. THIS LOOKS LIKE WE SHOULD HAVE COMBS IN IT. RIGHT?>>YEAH. LET’S POUR THAT INTO HERE. WE’RE GOING TO TRY IT WITH THE BATTERIES.>>Jimmy: A INTO B? WITHOUT THE BATTERIES.>>YEAH, WITHOUT THE BATTERIES.>>Jimmy: IS THIS DANGEROUS AT THIS POINT?>>NO. THE ANTIOXIDANTS ARE WORKING AND THEY REVERSE THE ACTION.>>Jimmy: WOW. WITHOUT THE BATTERIES NOTHING HAPPENS.>>WE HAVE THAT NICE LITTLE MAGICAL CHEMICAL CHANGE. NOW LET’S SWITCH OVER. NOW WE HAVE AN ACID HERE AND I’VE GOT THIS RED CLOTH THAT IS STAINED WITH SOMETHING CALLED CONGO RED. WHICH IS ALSO AN INDICATOR. SO IF YOU TAKE THAT AND THEN DIP IT INTO THIS ACID SOLUTION.>>DIP IT OR DROP IT?>>YOU CAN JUST DIP IT IN. AND THEN WE GET OUR BLUE BACK. OH, LOOK AT THAT. ISN’T THAT PRETTY? ALL THE WAY IN.>>Jimmy: NOT REALLY.>>ALL THE WAY IN. DIP IT IN. THERE WE GO. SO WE’VE GOT OUR BLUE BACK.>>Jimmy: OKAY.>>THAT’S KIND OF COOL.>>Jimmy: WOW. IT REALLY DID CHANGE COLORS.>>YEAH, IT ACTUALLY CHANGED COLORS. BUT THE SOLUTION STAYS CLEAR. NOW, HARRISON, YOU CAN TAKE THAT OUT.>>MM-HMM. [ LAUGHTER ]>>AND THEN PUT THAT IN HERE. AND THIS HAS A BASE SOLUTION.>>Jimmy: UH-HUH. REMEMBER, HE IS A NATIONAL TREASURE.>>YEAH, I KNOW THAT. [ LAUGHTER ]>>Jimmy: OKAY. HERE WE GO. THE BASE SOLUTION.>>GIVE IT A LITTLE STIR HERE. AND WATCH THIS. WE GET OUR RED BACK. SEE?>>Jimmy: OUR RIGHT. THAT IS RED.>>NOW, IF WE WANT THE BEST OF BOTH WORLDS, YOU CAN TAKE THAT OUT OF THERE, JIMMY, AND SQUEEZE IT OUT INTO THIS ONE, WHICH HAS A LITTLE BIT OF FIMOL THEY’LLINE SOLUTION AND THEN WE GET A LITTLE BIT OF BOTH COLORS. [ APPLAUSE ]>>Jimmy: AND CORRECT ME IF I’M WRONG BUT THIS IS HOW THEY COME UP WITH THE NEW FLAVORS OF MOUNTAIN DEW, RIGHT? [ LAUGHTER ]>>YES.>>BUT WAIT A SECOND. THIS IS SCIENCE, RIGHT?>>YES. IT’S REAL SCIENCE.>>Jimmy: THIS IS SCIENCE. LET ME WIPE MY HAND ON THIS TOWEL.>>THEN YOU CAN TAKE YOUR GLOVES OFF.>>AND WHAT DO WE HAVE NEXT?>>LET’S DO A LITTLE PHYSICS.>>Jimmy: THIS IS, AND CORRECT ME IF I’M WRONG ON THIS, THIS IS SOME KIND OF A SEX MACHINE, RIGHT? [ LAUGHTER ]>>NO, JIMMY. NO.>>ALLOW ME TO CORRECT YOU. YOU’RE WRONG. YOU’RE WRONG. THAT’S PROBABLY FOR THE BEST.>>SO WHAT WE’VE GOT HERE IS A 15-POUND BOWLING BALL WITH THREE-INCH SPIKES OUT OF IT. THE SPIKES ARE UNNECESSARY BUT I THOUGHT THEY’D BE KIND OF COOL.>>Jimmy: ALL RIGHT.>>AND UNDERNEATH THAT WE HAVE A CERAMIC PIG. A LITTLE PIGGY BANK.>>Jimmy: YES, WE’VE SEEN IT.>>HERE’S WHAT I’M GOING TO DO. I’M JUST GOING TO MAKE SURE IT’S LINED UP. WE’RE GOING TO DO FIRST A TEST OF GRAVITY HERE. I WANT TO MAKE SURE GRAVITY’S STILL WORKING. HARRISON, IF YOU WANT TO COME BACK HERE — >>TAKE MY GLASSES?>>YEAH, KEEP THOSE ON FOR THE MOMENT.>>Jimmy: KEEP THEM ON. SAFETY FIRST.>>THIS IS GOING TO BE A LITTLE HEAVY. [ LAUGHTER ] FOCUS. FOCUS. HERE WE GO. SO NOW WHAT WE’RE GOING TO DO IS ON THE COUNT OF THREE WE’RE GOING TO DROP THAT AND SEE HOW GRAVITY AFFECTS.>>THAT WILL BREAK THE PIGGY BANK.>>IT MIGHT DO THAT. ARE YOU OKAY WITH THAT?>>Jimmy: IT’S NOT MY KID’S. SO I’M FINE WITH IT.>>HERE WE GO. IN THREE, TWO, ONE. THERE WE GO.>>YOU’RE RIGHT. IT DID WORK.>>GRAVITY WORKS.>>Jimmy: OH, WE HAVE AN INSTANT REPLAY HERE WE’RE GOING TO LOOK AT JUST SO WE CAN PROVE THE EFFECT ON SOMETHING HEAVY ON SOMETHING FRAGILE. LOOK AT THAT. [ LAUGHTER ]>>ALL RIGHT. SO NOW WE’RE GOING TO MAKE — WE’RE GOING TO DO THE SAME THING BUT WE’RE GOING TO MAKE ONE LITTLE CHANGE. I’M JUST GOING TO PUT A TWO-POUND BAG ON HERE. THAT’S THE ONLY THING WE’RE GOING TO CHANGE. BUT INSTEAD OF A PIGGY BANK I WENT AROUND YOUR OFFICE TODAY AND I ASKED THEM WHAT IS SOMETHING THAT IS REALLY VALUABLE TO JIMMY? AND THEY CAME UP WITH IT OVER THERE. I DON’T KNOW IF YOU WANT TO BRING THAT OVER.>>Jimmy: OH, WHAT IS THIS? OH, NO. NO, NO, NO, NO. THIS IS MY “SOUL TRAIN” AWARD.

EVERYTHING’S THE SAME.>>Jimmy: THIS DOESN’T SEEM LIKE IT’S GOING TO BE GOOD FOR ME.>>NOW, IF ALL GOES WELL THIS BAG WILL CREATE ENOUGH CENT RIP TAL FORCE THAT IT WILL ACTUALLY AS IT FALLS STOP IT IN THE PATH. THEN HOPEFULLY FRICTION WILL CONTINUE TO WRAP AROUND THAT UPPER POLE AND KEEP IT IN PLACE.>>Jimmy: IF NOT I AM GOING TO SUE YOU. [ LAUGHTER ]>>I’M A LITTLE AFRAID. HERE WE GO. ARE YOU READY?>>Jimmy: YES.>>THREE, TWO, ONE.>>Jimmy: OOH.>>THAT WAS CLOSE!>>YOU DID HIT IT.>>BUT IT’S FINE.>>Jimmy: YOU’RE GOING TO DROP IT. LET’S LOOK AT AN INSTANT REPLAY TO SHOW WHAT HAPPENS WHEN SOMETHING DOESN’T GET CRUSHED.>>JUST A TAP.>>Jimmy: YOU DID COME A LITTLE TOO CLOSE FOR MY LIKING. WE’RE GOING TO TAKE A BREAK. WHAT ARE WE GOING TO DO WHEN WE COME BACK? SOMETHING BIG?>>ENGINEERING. AND IT COULD BE MESSY.>>Jimmy: OKAY. VERY GOOD. WE’LL BE BACK WITH SCIENCE BOB. WELCOME BACK. SCIENCE BOB IS HERE. HARRISON FORD IS HERE. WE ARE DOING FUN THINGS WITH SCIENCE. AND WHAT FUN THING ARE WE GOING TO DO WITH SCIENCE NEXT?>>WE’RE GOING TO TAKE A QUICK LOOK AT SOME ENGINEERING. SO BACK AT MY LITTLE SHOP I HAVE THIS ONGOING BATTLE WITH THAT SORT OF LIKE PARTY STRING STUFF, YOU KNOW THE STUFF — >>Jimmy: OH, YES.

THERE WE GO.>>Jimmy: WHAT DO YOU CALL THIS?>>SO THIS GUY — THIS GUY INSTEAD OF SHOOTING ONE OR TWO CANS AT A TIME IS DESIGNED TO SHOOT 30 CANS AT A TIME.>>Jimmy: SO THIS IS A REAL TIME SAVER, THEN.>>IT’S REALLY A TIME SAVER. AND A LOT OF ENGINEERING. THERE’S A LOT OF KIND OF MECHANICAL ADVANTAGES. THERE’S A LOT OF TESTING. FOR EXAMPLE, THESE CANS ARE ONLY DESIGNED TO SHOOT VERTICALLY. SO WE HAD TO COME UP WITH A WAY TO MAKE THEM SHOOT HORIZONTALLY. WE HAD TO MAKE BRAND NEW NOZZLES FOR THEM.>>Jimmy: A LOT OF WASTED TIME IS BASICALLY — >>NO, NO, NO. IT’S GOING TO MAKE PEOPLE SMILE. THAT’S WHAT IT’S ALL ABOUT.>>Jimmy: OKAY. GREAT.>>SO I THOUGHT WE’D TEST IT OUT. GUILLERMO HAS ACTUALLY OFFERED TO BE OUR SUBJECT.>>Jimmy: DID YOU OFFER YOURSELF FOR THIS, GUILLERMO OR WERE YOU RECRUITED?>>Guillermo: I DID OFFER MYSELF.>>WE DON’T WANT GUILLERMO TO BE COMPLETELY DEFENSELESS. THOSE TWO ARE FOR YOU. JIMMY, BASICALLY THE WAY IT WORKS IS YOU’RE GOING TO HOLD THAT. YOU’RE GOING TO PULL THAT HANDLE OUT.
