Sargent Welch Coupled Harmonic Oscillator

PIRA 3A70.21

No, this is not a set of Newton's Balls. The Sargent Welch "Oscillator" is a set of coupled pendula. Start one oscillating with the others still. It's amplitude will decrease, while the ones next to it will begin to oscillate with increasing amplitude. Eventually, the first one will be still, while the ones farthest from it have the largest amplitude.
