Kevyn: They are getting warm but the heat dissipates too quickly. That means my contact point is too large.
Kevyn: I need a very small contact point, isolated and contained, so the heat can build up. I also need some serious mechanical advantage so I can rub the sticks faster.
Kevyn: I think that means I need three sticks.
