For years there has been loads of videos showing the Coca Cola and Mentos experiment. If you are unaware of it, basically if you drop a Mentos mint into a bottle of Diet Coke and shake it up, the bottle explodes and sometimes turned into a rocket.

The experiment below is even more surprising and also a little disconcerting to anyone who drinks coke. For those with a little knowledge of science, Coke has an acidic pH between 2.5 and 4.5. It can be used to clean car engines or to take the tarnish off a coin. Yes this is the stuff you put in your stomach! If you then mix Coke with a liquid with a normal PH balance such as milk, what would happen? The answer is, something gross happens. 

First pour a little bit of milk into a bottle of Coca Cola.

Next put the lid on the bottle and wait for 6 hours while the reaction takes place.

As you can see, the top of the Coke turns into a clear-ish browny liquid.
