Here are a couple of videos that I enjoyed.  This first one is a video we shot of my oldest daughter’s science experiment.  I’m just glad she didn’t pick the volcano!

I think we spent about $30 for the stuff to do this.  By the way the magic ingredient here is DRY ICE!  Makes the tornado easier to see.

Next is one we “the family” really enjoy.  I think that enjoyment has more to do with it happening to us that any real entertainment quality.  I add it just because I find it funny.
