Here's a fun experiment you can try at home while the kids are out of school for winter break or when you want to show your friends a really neat party trick.

This experiment proves what a lot of people probably already know, but don't think about. All you need to do is take a quick look at the ingredients and you'll find one of the primary ingredients in cola, next to carbonated water and sugar, is food coloring.

As a caution, you'll want to dispose of the cola and bleach solution once the experiment is done so someone doesn't think it's actually drinkable.
