You can modify it for the coke and mentos thing though. I have seen the coke and mentos experiment and that's pretty powerful. Having it under pressure would be quite interesting. Good Luck and be careful!!

Merry CHRISTmas. :)

Answer 2

actually, the reaction is not a chemical process, but rather a physical reaction. As the mentos sink to the bottom of the bottle, the bubbles form. I was also under the impression that Pepsi is not used, it is diet
coke

Answer 3

Take 1 full bottle of DIET COKE not pepsi.

Unscrew the top, add 3-5 mentos.

RUN, and watch as the foam cascades out.


Unfortunately, you cannot make a rocket out of this, as the thrust produced by the "rocket" is not greater than the weight of the "rocket".

Check out mythbusters, they tried it, didn't work.

Answer 4

You don't need a pump.
Use -- Diet-- and three Mentos.
But you have to make a spout very narrow.
Myth busters says "Don't try this at home"
