Beakman uses ping pong balls to simulate electrons. He rolls them down a pipe that gets narrower so they pile up (resistance). In a light bulb, the resistance causes the coil to heat up and make light.
Beakman challenge: put a skewer through a balloon without popping it. The stretched rubber acts like a coil, and when it's stretched, it pushes away, and the balloon will pop. However, if you find a part of the rubber that's not stretched (the ends), then it will push together and allow the skewer to go through.
