Re: [Phys-l] heat/energy

A great technique for WILDERNESS SURVIVAL! ;-)

One year, I had the students try making fire by the friction of two peices of wood. I had a group of boys who did it the traditional way by using a wooden dowel and a loose bow to rotate the dowel at a fast rate. I also had a group of girls, who figured it out a faster way of doing it, by placing the dowel in the chuck of a drill. After a few minutes of pressing it hard into the bottom board, they quickly got smoke and fire.
