Friction Fire Mishaps

"Hi, I'm Mark Sullivan for Expert Village. And today, you're going to learn how to start a fire with friction. We may be onto something here with the square part of the spindle. Okay, let's see. I'm going to do it this way. Then we'll hold this in place while we hold our top bearing on, which is a rock. And then, we'll pull this in place like this and get our bearing into there. Now let's see what this does for us. Okay, it is going in both directions. This is what we're after right here. Okay, I'm going to put the rope up a little bit higher. We're going to try it this way again and see if we can get it to spinning in both directions. Oh, look, that's spinning very nicely. This is exactly what we want. You see this? So this is what you're after is this arrangement right here. And then you just keep doing this and look down at the point of contact and you may - oops, we've got to keep this going. My top bearing came out. I'm wearing away something here."
