I made a potato cannon.
It shoots much farther than Adriel's trebuchet!
It has a 2" wide barrel and a 3" wide combustion chamber, and is about 3 feet long.
I used a grill igniter for the spark and denatured alcohol (Heet) for fuel.
Here is another picture of it:

I haven't shot it for awhile because we ran out of potatoes.
Very cool Doran. You'll have to have a separate garden just for potatoes this summer!
