This is why you should never bring a phone to a knife fight... or maybe you should. One false move and you got yourself a flamethrower.

I have no idea how real this video is or what type of phones use this battery -- the consensus in the YouTube comments is that neither Samsung phones nor iPhones use this kind -- but I can tell you that I'm going to remember this video every time I put my phone to my ear from now on.

This reminds of the first time I saw 'Ghoulies 2' as a kid. Did I really believe a ghoulie would hide in the toilet and eat my butt when I sat down? Not really, but you can bet your ass I inspected the toilet before sitting for about 4 years after. Some images just stay with you.
