Lariat chain

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[1] at the Exploratorium in San Francisco.

The 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.

The speed of the chain is arranged to equal the wave speed of transverse waves,[2] so that waves moving against the motion of the chain appear to be standing still.
