- How to make and fire your very own Polish Cannon
-
- Created and typed by: Bullwinkle Moose
-
- Part 1: The Polish Cannon Concept
-
- The polish cannon was invented for all of you who would love to have a gun-
- type
- weopon or just something fun that shoots things. With about $1.50 worth of
- lighter fluid and materials around the home, you can make your very own
- cannon.
-
- Part 2: Building the Cannon
-
- Materials:
-
- 1: 2 or 3 empty Cambells Chunky Soup cans with BOTH ends cut out (or a can of
- the same exact size)
-
- 2: An empty coke can (or similar aluminum can)
-
- 3: Duct Tape
-
- 4: Tennis Balls
-
- 5: a Can Opener (like the ones used to open Hawaiian Punch or Hi-C cans)
-
- Ok. Take your empty soup cans and make sure both ends are cut out of all of
- them. 3 cans is best but 2 will do. To make sure you have the right size
- cans, put a tennis ball in one and make sure it fits snugly but not too
- tight. Place the cans end to end and tape them together making sure the
- ends of the cans are exactly aligned. After taping, slide the tennis ball
- through to make sure there are no spots where it gets caught.
-
- Now take the empty coke can in your hand. Do not cut the top out of this.
- Instead, take the can opener and make 3 holes. There should now be the
- drinking hole and the 3 additional holes you made. Fit the front end of the
- can into one end of the soup can tube. The top of the can should fit inside.
- Now tape this on. Make a hole in the side of the coke can. Make the hole
- about half the size of a penny (not too small though).
-
- You have now made your cannon.
-
- Part 3: Firing the cannon
-
- Set the cannon up with the open soup-can end pointed out in to a field or at
- the target. Then put a tennis ball in the end and push it all the way down.
- It should stop at the coke can top. Now take your lighter fluid and sqirt
- about 1/8 inch of liquid in to the coke can through the hole you made.
- Place your thumb over the hole and shake the fluid. This will make a
- flammable gas. After a good shaking, quickly move your thumb away and light
- the hole with a lighter or match. Whoosh! The ball should launch.
-
- Part 4: Problems and warnings
-
- About 30% of my cannon shots fail. Here are some reasons:
- 1: not enough shaking
- 2: too little OR too MUCH lighter fluid
- 3: hole in side of can is too big
- 4: tennis ball is too tight
- 5: gas never lit because of a small hole
-
- Warnings:
- 1: do not hold the cannon when firing (duh....) it has a lot of kick
- 2: be careful when lighting. On most failed attempts, instead of the rush
- of heat and flames shooting the ball, it shoots out the firing hole.
- 3: Make sure the cannon is supported well in the back when firing.
