A Lariat chain is a loop of chain that hangs off, and is spun by a wheel. It is often used as a science exhibit or a toy.
The original Lariat Chain was created in 1986 by Norman Tuck, as an Artist-in-Residence project at the Exploratorium in San Francisco.
Lariat Chain was developed from an earlier Tuck piece entitled Chain Reaction (1984). Chain Reaction was hand cranked, and utilized a heavy chain attached by magnets onto an iron flywheel. As in Lariat Chain, Chain Reaction used a brush to disrupt the motion of the traveling chain.
The speed of the chain is arranged to equal the wave speed of normantuck.com

The speed of the chain is arranged to equal the wave speed of transverse wave
In physics, a transverse wave is a wave whose oscillations are perpendicular to the direction of the wave's advance. This is in contrast to a longitudinal wave which travels in the direction of its oscillations. Water waves are an example of t ...
