but yeah, grill ingniter and a can of starter fluid would launch a potatoe out of a 5 foot barrel about 150 yards or more.

- grill push igniters
- 5 ft. 2" pvc barrels
-around 2 ft. 3" pvc chambers. you can also use 4" pvc..
ill post pics up today.
im going to mess around with the size of the chambers so i have enough materials to make two. everything you need will be around $30-50bucks to make one.
