Old school tin-can cannon
Posted: Thu Apr 24, 2008 2:29 am
OK guys, here's a little historical perspective for ya.
Back in 1971, when I was in the 8th grade, a guy whose name I don't even remember, brought a tin-can cannon to school. It used lighter fluid for fuel and a tennis ball for ammo. We went out behind the school after school and he shot it for me. I was so taken with the thing, he actually gave it to me.
So this evening, I decided to take a few minutes and build a replica of my 8th grade cannon.
Specs:
- Chamber and barrel made from 4 vegetable tin cans
- Tops and bottoms are cut out of 3 cans, the 4th has only a small hole in the bottom and several old fashion can opener holes in the top. Use a vegetable that is small like corn so that you can shake it all out of the openings...see pics.
- Cans are taped together with duct or gaff tape (original used electrical tape in 1971)
- Fuel is cigarette lighter fluid
- Ignition is a lit match to a match hole on the back of the cannon
- Ammo is a tennis ball; it can also be shot without any ammo and used as a noise maker
Here's the pics
Shooting this thing involved a small squirt of lighter fluid in the match hole and then "airing" the chamber by shaking the cannon and slurping fresh air into the barrel and thus the chamber...5-10 seconds or so. Load your tennis ball and prop the cannon up in such a way that you have access to the match hole in the rear. Aim the cannon in a safe direction and light the match hole...
These are actually considered the precursor to today's PVC combustion cannons. There was a story describing these on Spudtech's site at one time, not sure if it's still there or not.
Try it yourself...you can make one in about 30 minutes with nothing but kitchen utensils.
