Electrical Explosions

The first time I heard about an explosion was about a year ago through gmail chat.   Sitemate:  Umm....Jennifer, my water heater in the bathroom just exploded. Me: Oh that is scary. Then I got to hear an explosion for myself.  The other week my PC provided water distiller that removes heavy metals and minerals went POP, with a nice flashy bright explosion.  Now I am truly cursed.  I helped my sitemate carry her HEAVY water distiller back to Chengdu when she COS'd (close of service) and now I have TWO of them to return to Chengdu.  The PC medical officer sent me a new one. The third explosion was today.  As students were standing up to do the Cupid Shuffle, we heard an explosive POP and the glass from a florescent light bulb dangerously rained upon the four of them.
