Use a Bar-B-Que igniter, save a camra. Or go all out, get a stun gun set up.

try using something like 'start ya bastard' for fuel. any car starting sprays. the couple of types i have tried contain like 24% ether. very good for this type of application. don't use wd-40 or flyspray or anything like that you need something that wont easily gum up or liquify on the walls of the chamber. because if you use something that sticks to the walls it doesn't explode and then when you try again the new fuel finds it much easier to stick aswell and you need to let it dry or something.
