Mini Potato Cannon

A few notes before we start: There are MANY potato cannon recipes out there. I did not invent the mini potato cannon. I merely made my own out of inspiration. Second, this is more of a documentary than an instructable, as I made this before my instructables account. It gives you step by step instructions for what I did and pictures of the finished product but no pictures of the actual process. But you can still make your own very easily, and I will tell you what I did to make one.

**Disclaimer: This potato cannon shoots virtually anything small enough to fit in the barrel at a high velocity. This potato cannon also uses hairspray, which is extremely flammable. It is recommended that you wear safety goggle and keep flammable objects out of reach (yourself included). I am not responsible for any damage you cause to ANYTHING**

Step 1 Get the materials

The materials I used were very simple. It cost me a total of $0.00 to get them all.


You will need:

1. Tylenol container (or any non-perscription medicine bottle)

2. Pentube (or any sturdy, hollow cylinder)

3. Piezoelectric sparker (anything with a high enough voltage will work, but the PE sparker is the smallest and the cheapest)


The piezoelectric sparker is probably the hardest to find. I got mine from an old barbecue lighter.

Tools you will need:

1. Hot glue gun

2. Soldering Iron (optional)

3. Sharp tool or rotary cutter

Geee... Real smart. "Hey dude, I have a great idea. Lets put some dangerous chemical propellant in a sealed tube made from flammable cardboard, then stuff a projectile in, and have explode in our hand!"
"Wow great idea! I love first degree burns all over my hands too!"\
