Science Cabaret: Why don’t bikes fall down?

You can balance a bike with hands on the handlebars. Or off. And, surprising if you haven’t seen it, a bike can balance itself, with no person touching it. When viewed from the back, a bicycle looks like a stick balanced on end. If it tips a little, gravity pulls it down more.
