The Thors Hammer Experiment!
 
This is actually a really cool experiment.  Turns out one of the biggest hazards in dealing with alkali metal demonstrations is the fact they behave erratically.  This is a way of getting an controlled explosion out of the metal essentially at will.  As such this experiment will become a core part of alkali metal demonstrations in school classrooms around the world for centuries to come..... and it all started here... and thanks to your support :-)
