Science guy NightHawkInLight takes a popular pendulum physics demonstration and amps it up. He starts out with a large pendulum made from metal nuts and varying lengths of strings for the bright shots, then covers them with tape and fluorescent paint to make them glow brightly under UV light.
We’ve seen some pretty cool pendulum wave demonstrations before, but never one at this scale. Back in 2012, Appalachian State University teacher Jeff Goodman built this oversize physics demo rig using 16 bowling balls, and a series of chimes which play sounds as the balls brush across.
Looking for a cool demo to show off your fancy new HDR display? Look no further than this CGI video from self-proclaimed “GPU melter” lotsalote, in which a set of brightly-illuminated pendulums swing back and forth against a dark background. The 4K 60p footage really pops off the screen with its high contrast imagery.
