2 years ago my and 2 friends were setting off a big collection of fireworks that i had. once we were done we gathered up all the remains and lit them on fire, as well as anything else we could find that might have been worth burning, including an axe can (can you see where this is going?)
anyways, the fire was dying down, and we were just lying about 10 feet away from the fire on the grass when suddenly the axe can erupted and a huge mushroom of flame shot up into the air and depris flew everywhere. one of my friends burned his leg, but other than that, it was pretty awesome
