BP Explosion from Impact?

[paulvallandigham]

Guys: Its called a Fire Piston, and works on the principle of compression of gas. Unlike the barrel of a flintlock or percussion gun, there is no escape valve, or hole in the bottom to relieve the pressure. The pressure has to be very high to produce the fire. I have one, and after some practice can usually have a glowing ember in my tinder by my third attempt. I am still faster using flint and steel, And almost as fast using a bow and drill ( spindle) for firemaking. If you check[url] TrackerTrail.com[/url], there is an entire list of primitive ways to start fire, and comments or articles on each of them.

Tis the same principle applied for fire pistons. I know a home made fire piston will set off match heads with a bang, don't ask me how I know.

Ditto, along with a very wet and sudsy kitchen mop to clean up the fouling.
