Place three seemingly identical spheres on a 3-foot horizontal track touching each other. Slowly roll another sphere slowly into the spheres at rest. Wow! All of a sudden one sphere takes off with tremendous velocity. Has the system gained energy? Could this be the basis of a perpetual motion machine? Hmm... Great for open-ended discovery! Colors may vary. Also available, six additional spheres for additional experimentation.
