This is a very cheap and simple experiment. You just buy a big bottle of diet coke and some mentos mints. Drop some of the mentos in the coke and run (you will get wet if you don't)!
I am a huge fan of chemistry and wild experiments. This is why I made this site, so that you could visit my collection of experiments that I have found on the internet. This is the place to stay if you like big explotions, burning flames and big BANGS!!
