@her0_0f_time: That was what I was thinking (w/ regard to the saran wrap prank), except that at least this way everything stays in the bowl instead of running onto the floor. Also, I think that once the ice all melts and everything gets back to room temperature it would become basically liquid again allowing it to be…

I've always wondered what would happen if you added (colorless) gelatin to a toilet bowl and then added ice. Anyone ever done this?

@Josh_Geyer: Either way, I'm not entirely sure what the means of ignition was. Maybe the ball bearing projectile absorbed enough heat from the powder burning to get hot enough to ignite whatever it was, but I'm not so sure.
