Each sphere is moving in a straight line But watch

There's a magnet under the plastic that keeps everything moving. At least one of the balls snaps into place.

@Soapy_Wit_Tank The round black thing is a magnet. 🧲 And the balls are metal !

Where can I buy this @grok

Still i prefer golf ⛳

OCD ecstasy

This like how LED neon strip works
