Introduction: 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.)
Step 1: Materials Needed
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
10. Thumbtacks (Not pictured)
11. Tape (Not pictured)
Step 2: 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.
Step 3: Make the Barrel
Use your pliers to pull out the ink cartridge out of the pen. Then, make a hole in the other side.
Step 4: 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.
Step 5: Take Apart the Lighter
Put the combustion chamber and barrel aside and get your lighter. Remove any screws you see.
Step 6: Find the Sparker
Find the little sparker thing and attach the thumbtacks to the ends of the wires.
Step 7: 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!
