    This is a great video for demoing ideas about pressure and gas laws, an in particular the how boiling point increases with pressure.  Popcorn pops because the water inside flashes to steam and expands. If you put the system under sufficient pressure it won't do this … until the pressure is released, and all of the popcorn pops at the same time.
