Re: [Phys-l] heat/energy

You suggest a reason to backpack a battery driven drill?

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.
