How to Make a Mini-potato Cannon
Have you ever wanted to build a potato gun but never had the time? Well, now you can! This mini potato gun will only take 10-20 minutes and will entertain you for hours. (This is my first instructable.)
Materials Needed
Materials:
1. Mini screw drivers
2. Film canister
3. Bic Longnose Lighter
4. Knife or drill
5. Papermate pen
6. A aerosol deodorant
7. Hot glue gun
8. Potato or BB's
9. Pliers
10. Thumbtacks (Not pictured)
11. Tape (Not pictured)
Make a Hole for the Barrel
In this step, you do exactly what the title says. Use your knife or drill to make a hole in the bottom of the film canister for the barrel. The film canister is your combustion chamber.
Make the Barrel
Use your pliers to pull out the ink cartridge out of the pen. Then, make a hole in the other side.
Put the Barrel and Combustion Chamber Together
Put the barrel in the hole you made in step 2. Then, hot glue and tape it together.
Take Apart the Lighter
Put the combustion chamber and barrel aside and get your lighter. Remove any screws you see.
Find the Sparker
Find the little sparker thing and attach the thumbtacks to the ends of the wires.
Last Step: Finish It
Stick the thumbtacks with the wires into the film canister a little ways apart. Secure the sparker and you're done!
