-ignitor can be taped down
-excess wire can be cut off or taped down

~When firing only spray a little propellent in the chamber or it wont shoot.
~When you shoot always hold the cap on tightly or it will shoot off and hit you, I know this for a fact.
~One very tiny amount of spray is good for at least 2 shots if not more
~if it doesn't shoot check for a spark, if there isn't one its shorting out somewhere
~if it wont shoot and there is a spark, you put to much propellant in
~tape around thumbtacks to avoid getting shocked

MAP Gas, Propane, or even that butane from the lighter you tore apart.
These are good propellants plus they burn a lot cleaner than aerosols.

I made the damn thing....at 12:00 AM ...was bored, relized I had nothing for fuel lol....ended up taking a pen cap and putting on an air duster can...fits perfect and launches the little potato pretty far....

so if anyone is lazy they can use that lol

Good little design though, hopefully mine works when i grab some hair spray tomorrow...

also ...i took a bbq lighter, drilled a hole in the cap and taped it onto it so it's like a little handle with a trigger on the cap
