Banana Hammer

I mentioned this in the previous post, and then found the video. A banana being used to hammer a nail into a board.

Hydrogen Balloon Explosion

So last night I went to a chemistry demonstration and among the various awesome things that I saw was nail being hammered into a board with a -400 degree F banana.  I also saw a balloon filled with hydrogen and then ignited.  If your ever curious why we use helium instead of hydrogen in our balloons, just check out the high speed video below.
