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

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)

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!
