Action Lab Shorts puts perpetual motion in a vacuum chamber

An older graphite experiment supplies the science during a week without new clips from The Action Lab.

Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.

The Strange Limit of Frictionless Motion

The disc stops anyway. In "The Strange Limit of Frictionless Motion," a piece of graphite floats above magnets, spins inside a vacuum chamber and eventually gives up, despite most of the air having been removed.

The interesting part is why. The host initially expresses frustration that reducing the pressure barely extends the spin. His explanation: across this pressure range, air viscosity matters more than the amount of air left. Even at much lower pressures, tiny eddy currents caused by imperfections in the graphite and magnets would prevent endless rotation.

Action Lab Shorts, which posts short-form excerpts from The Action Lab, added nothing new this week. Its existing catalog nevertheless gathered roughly 260,000 views. The graphite experiment has the strongest daily momentum among its highlighted older uploads, followed by "Can High Voltage Power Lines Light Up a Bulb In Your Hand?" and "World's Fastest 3D Printer."

Subscribers held steady, while daily views are running below the channel's usual pace. Among nearby science channels, NileBlue had a particularly substantial week; Stuff Made Here was quieter. For Action Lab Shorts, the useful discovery is tucked inside that apparently simple spinning disc: removing nearly all the air does not remove nearly all the drag.
