Mesmerizing to watch as it traces beautiful Lissajous patterns in sand.

Description

This pendulum is mesmerizing to watch as it traces beautiful Lissajous patterns in sand. A favorite of elementary school science tables, it can be used at upper levels to study harmonic motion as energy is transferred from a pendulum swinging in one plane to swinging in another plane at right angles. A Lissajous figure results from the two sine curves meeting at right angles. 22" tall!

I have had my pendulum for years..so long that the grooves have gotten too deep for it to work. Can I order a new wand ??? I need the wood wand and new sand. What would that cost if it is possible?
