Comments about Traditional Fire Piston:
I bought one from 3Rivers a couple of weeks ago. Like I said, it's a big kid's toy. I play with it every day until the novelty wears off. I'm gonna keep it in my backpack. Better to have it and not need it, than to need it and not have it.

Comments about Traditional Fire Piston:
I've not used this product, but have demonstrated the use of a fire piston in teaching college physics classes. The tinder is ignited because the temperature of the air trapped in the cylinder increases dramatically when it is compressed by the piston, as does any gas when it is compressed. The opposite effect occurs when a gas expands; it cools, which is the basis for modern air conditioning systems. In the case of the fire piston the compression takes place rapidly and heat cannot escape fast enough to keep the temperature from rising above the flash point of the tinder. There is some friction, but that is not what produces the fire as is the case with a traditional fire drill.
