What you Need

We used a large "fire piston" this is an ancient fire lighting device from SE Asia. The one we used is basically a large transparent bicycle pump, but with nowhere for the air to get out at the bottom.

When the plunger is pushed down very fast the cotton wool gets immensely hot and bursts into flames. This was used in the Burma, Malaysia Borneo region as a way of starting fires. These were made of horn or bamboo and would light a small piece of tinder. It is thought that Rudolf Diesel saw one of these and it gave him an idea..
