Pendulum Snake
"Pendulum snake" exhibit. Exploratorium, San Francisco, California, 2016.
The suspended balls swing back and forth at slightly different rates, determined by the length of the strings. Each ball completes a set number of swings in 30 seconds, from the longest (15 swings in 30 seconds) to the shortest (24 swings in 30 seconds). Set in motion together, the balls go in and out of several interesting patterns before they line up again after 30 seconds.
