This is my first Instructable so if it is a little unclear please let me know.
ok so this is how to make a mini potato launcher

Step 1: Stuf That You Will Nead.

what you will need:

1. about 4 ish inches of 3 1/4 id (internal diameter) PVC pipe.
2. a grill igniter the kind with the red button that goes click when the button is pushed.
3. a very sharp knife.
4. a hot glue gun w. glue.
5. misc PVC parts like elbows, caps, etc.
6. ammo like a potato, etc.
7. fuel source like propane torch, butane lighter, hare spray, axe, etc.

Step 2: Putting It Together.

first take the wire and insert it into the small hole on the igniter. make sure that the wire is touching the spring inside the igniter. then rap the wire around the smaller end of the igniter and make a hook on one end and align the tip of the wire with the mettle nib on the end of the igniter. now insert the hole thing into the PVC pipe and seal with a bead of hot glue.

Step 3: Haveing Some Fun.

ok now that you have your mini potato gun their are a few things you can do like if you take a PVC cap and drill a hole big a nuff to insert the body of a bic pen and hot glue them together.

hoe to charge it i used ny dads propane torch but i think that a butane lighter wold work or some hair spray, axe, etc. so go have some fun''.
