Surprising Pepsi Challenge

video Surprising Pepsi Challenge
This incredibly simple experiment is baffling to many and actually makes physics fun!?! Here's one way to do it, but using a swimming pool is even better. Feel free to comment on the reason that this happens.

The diet floats because it doesn't have sugar in it. This changes the density and such. Or maybe little elfs are holding the diet one up. I think it's the first one, but I can't remember though.

Haha. Oh no...I thought I shopped all of the elves out. You are good!

Well, my sixth grade science teacher is the one you should be thanking. Thanks Mr. G!

Mr. G

Hes the superman of science
and he loves to play with fire
and the things to do
you can do
if you so desire
to try this at home with Mr. G.

Sorry I dont no if youve ever seen "do try this at home" but when you mention science and mr g i sing that song (=

no, the elves hold the regular one down...like a beach ball only they're better at it than me.

Oh that's right. I forget they hold it DOWN. I had it reversed, thanks!
The diet has more co2 thats why you use it only with the mentos expriment

That may be true, but the density of the diet is less than the density of water. The density of the regular is greater than the density of water. That's why you see the result shown. Thanks for watching!
