How to make a spark for a potato gun?

Question

I have succesfully made a potato gun. Except i used the igniter thing for a house lighter the large ones. and it worked. But the wires would always move after every shot. So i would always have to go back and fix them is there anything i can do to make a spark happen everytime?

Answer 1

I used the igniter from a gas grill. Try running in 2 screws in to the chamber and wrap the wires around them, this has always worked for me.

Answer 2

you could use the pvc cement that you used/ should have used to secure the wires- if the wires are inside the combustion chamber, DO NOT TAPE THEM- this could ignite inside of the pvc and catch fire when the spark is created

Answer 3
