Potato Cannons are devices that can be both fun, if you use them with caution, or dangerous, if used improperly. One of these babies acan launch a potato 100-200 yards at speeds of up to 100mph. Cool eh?!?!
Just Remember one thing...I'm not responsible for your stupidity!!!!!

This is a picture I drew of my Potato Cannon.
This is what The Age Of The Spud is all about!!!

To build a one of these ABS artilary cannons you will need the following:

3' of 1-1/2" ABS pipe
2' of 3" ABS pipe
1-1/2" to 3" reducer
3" clean-out and end cap
ABS glue
bolt and nut
B-B-Q ignitor
Duct tape (If you can't do it, duct it...If you can't dcut it, don't do it!!)
Epoxy glue

Assembely instructions:

1. Drill a hole in the 3" ABS (or chamber) pipe and insert bothe leadt of the ignitor into the chamber. If there is only one lead then attach a wire to the metal on the push-button part of the ignitor. Then epoxy glue it in place.

2. Attach the 1-1/2" to the 3" with the reducer and glue in place with the ABS glue.

3. Glue the clean-out to the back of the chamber (leave the cap off to exhaust the gasses)

4. Drill a hole in the barrel close to the chamber, about 2" from the reducer, (1-1/2" ABS pipe) and insert the bolt. screw nut onto the end.

5. Use the duct tape to attach the button to the cannon (usually placed on the reducer).

This picture shows how the individual parts fit together.

Firing:

You will need some potatoes and some hair spray (The airosaul type is HIGHLY recomended!!)and a long stick.  (Broken hockey sticks are perfect!)

1. Open chamber and sray in the hair spray then close.

2. placee potato in the end of the barrel (if it doesn't fit, MAKE IT FIT!!!) and push with stick until it hits the bolt.

3. Aim and push button until you hear a loud B O O M  and the potato fires out the end of the barrel at speeds of up to 100 mph!!! The potato should fly for 100-200 yards!!!

 

HOT TIPS

1.    Sharpen the tip or your barrel.  This way the potato will "go in" better.

2.       Spray a bit of alcohol in to the chamber with the hairspray.  The alcohol is the flammable  part of the hairspray.

3.     Experiment with different  types of ammo :
