How It Works

As the beads flow out to the floor, they form an arc up and out of the container. The force of gravity pulls down on the beads, but first they have to travel up out of the container. As one bead falls out, it pulls the next one out. The force of gravity pulls the weight down which causes the beads to be pulled out of the container.
