Educational Innovations Pit and Pendulum – for Science Classrooms, Zen Gardens, or Office Desktops – Replacement Sand Only

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
inches tall!
