HI.
I'M MISS NYLAH. >>AND I'M MISS SARAH.
AND TODAY WE'RE GONNA SHOW YOU A REACTION THAT'S REALLY FUN AND
REALLY MESSY. TO DO THIS EXPERIMENT, MAKE
SURE THAT YOU'RE OUTSIDE OR SOMEWHERE IT'S OKAY TO GET SUPER
STICKY AND MESSY. YOU'LL NEED A 20 OZ.
BOTTLE OF DIET SODA AND MENTOS CANDIES.
>>FIRST, PLACE YOUR SODA ON A FLAT SURFACE AND SLOWLY OPEN THE
CAP. NEXT, ADD YOUR MENTOS CANDIES
ALL AT ONCE AND STEP BACK. WE'RE GONNA START WITH ONE.
READY? READY. [FIZZING] >>WHAT WE JUST
SAW WAS A PHYSICAL
R
EACTION. THERE'S A LOT
OF CARBON DIOXIDE IN THE SODA, WHICH
IS WHAT MAKES IT FIZZY.
THE SURFACE OF THE MENTOS
CANDIES ARE COVERED IN
MICROSCOPIC LAYERS OF SUGAR. WHICH IS THE PERFECT PLACE FOR
THE CARBON DIOXIDE FIZZ TO ATTACH AND MAKE MORE BUBBLES.
AS THE BUBBLES ATTACH TO THE CANDIES, THE CANDIES ARE
ACTUALLY HEAVY ENOUGH TO SINK TO THE BOTTOM OF THE SODA BOTTLE. ONCE THEY REACH
THE BOTTOM, THE PRESSURE BUILDS
AND THAT'S WHAT CREATES A
SUPER MESSY AND FOAMY REACTION. SHOULD WE DO IT AGAIN?
YEA
H! HOW MANY CANDIES SHOULD WE ADD
THIS TIME, MISS SARAH? MORE.
OKAY. LET'S DO THREE.
READY? READY.
3, 2, 1! WOW!
WE HOPE YOU ENJOYED THIS MESSY REACTION.
SEE YOU NEXT TIME.
