The Perpetual Motion Dept.

Physics you can fidget with on a call.

Some people think with their hands, and this is their department: toys that click, balance, spin and run on temperature differentials. The selection criterion is that each one demonstrates something real — momentum, equilibrium, thermodynamics — and survives being handed to a curious coworker. Call-mute buttons exist for the clicky ones.

The Demonstrations

Kinetic and executive: the toys with a physics lesson inside.

Reading for the rabbit hole

Questions people ask

Which desk toys are safe to use on video calls?
The silent ones: balance sculptures, kinetic sand art, a Stirling engine on a warm mug. A Newton’s cradle is a metronome your microphone will faithfully broadcast to the whole standup — park it while unmuted.
Are these just gifts, or do people buy them for themselves?
Both, in about equal measure. They are the classic safe gift for an engineer precisely because the engineer would happily have bought one anyway.
