Mike and the boys made a "potato cannon" last evening.  They used lengths of pvc pipe in 2 inch and 3 inch diameters.  An adapter connects the smaller pipe to the larger one and a screw on cap with a hole drilled in it goes on the back end. 

Then they spray hairspray into the large back end and quickly screw the cap on.  A lighter is inserted into the hole and used to ignite the hairspray.  Talk about crazy! LOL

The explosion forces the missle (in this case snow) out of the cannon and into the air.

This and other fun ideas can be found in a book called Backyard Ballistics.

My hubby made one of those for our son when he was around 11 or so, now he is 25. That popper was so much fun, they would see how far they could get it to blow. Thanks for bringing back laughs from my past.
