A Lissajous Sand Pendulum

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. 21" tall!

Note: The pendulum is sold out, but we still have replacement sand available. Perfect for zen gardens, your science table, and much more!

I bought this because it was so neat looking. It is a conversation starter....used it as demo for my physics classes, too...find a place for it and keep it there.
