It's a well known fact that Mentos locked inside a bottle of Diet Coke will do anything to get out.  This has been documented on Youtube thousands of times, so the odds suggest that this was bound to happen.  See what happens through the eyes of the camera man, when Mentos bombs go wrong.

This had to be one of the scariest moments of the camera mans life, but I don't care!  I still laugh till I pee myself every  time I watch it.

These guys may have taken it to an extreme, but it's still cool to watch.
