Fire - Can of Coke and a chocolate bar
Yes, you CAN make a fire from a can of coke and a chocolate bar!

This idea was originally proposed by Andre Bourbeau to Rob Bicevskis about 6 years ago. I don't know if he is the one that came up with it in the first place. Thanks to Rob for bringing this method to my attention.

To make fire from a can of coke and a chocolate bar is actually quite easy, and you don't need any tools.
