Pendulum Wave Demonstration Kit for Physics
by American Scientific

With a series of 22mm steel balls evenly spaced out and each one suspended from a metal beam by varying lengths of cord, the pendulum wave is a captivating demonstration for all ages of students. Nine balls in total hang from the beam, and when pulled back and released simultaneously by the initiator stick, will swing back and forth to form a wave pattern and cycle through different phases at they visually simulate different phases, beats and frequencies due to the varying lengths at which they are suspended.

With its black wood and chromed metal look, the wave demonstrator could easily be used as an art installation, like the one built in the mountains of North Carolina by a professor and artist from Appalachian State University.

The pendulum wave demonstrator is simple to assemble, having just 3 pieces. When put together, it measures 11x8x14.75″ (HxWxL).
