Step 2: Build

Picture of Build
Cut the end off the pill bottle(the end without a cap).Stick in the two tacks into the bottle and make it so they almost touck(like a 3mm gap). Take a wired up ignighter and strip the ends and wrap them around each steel part of the tack and push down(if you dont know how to wire the ignighter too bad!).Tape the ignighter down to the bottle(make shure you can still press the botton).Wrap tape to the end of the pen tube so it snugly fits into the cut end of the bottle.Test for a good spark(rewire if it wont spark).

Put a bit of potato in the pen tube. spray a bit of hair spray in the screw end and put on the cap.

fire and enjoy

can we use perfume instead of hairspray?
instead of a bbq igniter, can you use the sparky end of one of those long lighters(an empty on)?

This is a great instructable (even if it wasnt your idea) i just finished making this mini spud gun and it worked perfectly. I used a Herron mini 25 capsule pack though, so there isnt alot of power but still it works well. Good Job!!
