Looks like an ordinary diet coke right? Well it is. Now here's something else:
Mentos Candies!
Why am I showing you pop and candy you ask? Well, let's see what happens when you mix the two together!
I know what I'M doing for the science fair this year!
See? Mix some Mentos and Diet coke, and you get a giant Diet Coke volcano! Why? Well according to Wikipedia: MythBusters concluded that the potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos, all contribute to formation of the foam.
The surface of the mint Mentos is covered with many small holes that increase the surface area available for reaction (and thus the quantity of reagents exposed to each other at any given time), thereby allowing CO2 bubbles to form with a rapidity and in a quantity that are responsible for the "jet"- or "geyser"-like nature of the effusion.
Diet coke may work the best, but it doesn't just work with that. Another pic from Wikipedia:
From left to right: Reaction of five drops of Mentos with Perrier, classic Coke, Sprite and Diet Coke.
Wikipedia sure comes in handy doesn't it?
Note: Get permission from and adult
and do this outside!
I've seen that experiment many times but that last picture was just :O O.O MIND BLOWING!!
