How can I make a piezo-kinetic igniter?
i want to build a mini potato cannon and i do not have any pre-made igniters that i can use for it. I wanted to make a piezo-kinetic igniter like the ones used in electric lighters. is there any link (or video preferably) with instructions on how to do this? I also want to know if you have to refill the gas chamber thingy after every shot of the potato cannon.
