While at the Maker Faire in San Mateo this past May, I ran into Rick Schertle's compressed air rocket launcher demo. Wow...such a simple design...and yet, really fun to play with! I decided that I would assemble one before my boy's 5th birthday...and I almost accomplished that. I didn't finish the stand for the launcher...but I did get something that worked put together.
If you're interested in doing a project like this...take a look at Rick's article in Make magazine...it is very helpful.
