Flame Tower!!!!!!!!!!!

This morning I got to go over to my old high school to see the Best Chemistry Teacher in the World^® (Mr. Vernon) do the Flame Tower^®, the coolest chemistry experiment there is.  He puts lycopodium powder into a metal tube with a candle at the bottom.  When there gets to be enough powder in the tube, it catches on fire and blow a large fireball out the top.  There is a YouTube video here.  (Sorry about the quality; it appears to have been shot with a cellphone.)  You really have to see it to get the true idea of what its like, though.
