Description
The Wilberforce’s Pendulum demonstrates the surprising phenomenum of the pairing of torsional and longitudinal oscillation in a mass-spring system.
The surprising effect is that, to a faraway observer, that is someone who doesn’t notice the torsional oscillation, it looks as if the vertical oscillation first slows down and eventually stops; then, seemingly without external interference, it starts growing up again as if it was under the influence of an invisible force.
It comes supplied without a table boss-head, a metal rod and a boss-head.
