Three things I'll add to this, Oxy-Acetilene balloon (get a nice lean cutting flame going then shut the tanks off and let the tip cool. Turn the tanks back on and fill the balloon), model rocket starter and thin wire, starter solenoid on his vehicle. I'll leave it to you how and where to assemble the three together.

I had an idiot in high school who threatened me for dating his ex girlfriend who dumped him for being an azzhole. I drove past and waved at him after he tried to start his pick up. He was standing next to it with a big wet spot in the front of his pants looking at me as I smiled and waved at him. Never heard another word.
