Here is where plans that are not to radical will be posted.
If you've got a fancy design go to the other plans thread.
If your model is pretty basic (nothing special, no spark strips, no chamber fan, etc.) by all means, post it here.

All you need is three or four metal cans that are about a tennis ball in diameter, a tennis ball, duct tape, hair spray (or other flammable substance), a lighter, and maybe some large PVC pipe for safety.
Construction:
Cut the bottoms out of all but one of the cans.
Cut a hole about the size of penny in the bottom of the can that still has a bottom.
Duct tape all the cans together, make sure the can that has a bottom is at the end.
Duct tape the tennis ball(s) so that they are a fairly snug fit into the cans.
You want the tennis ball to stick at the top but still be able to be pushed to the bottom with some force.
Launching:
Prop the mortar against a chair.
Spray some hairspray in the bottom through the hole you cut in the last can.
Load the tennis ball.
Put lighter near the hole at the bottom of the cans and light.
That should be some good fun. Kind of like a potato cannon but you can reuse your ammo.
