Just a lovely optical illusion and a very satisfying watch once you work it out
We do like one of these, a rather lovely optical illusion shared by Cliff Pickover on Twitter.
All the bearings are moving in a straight line. https://t.co/EFaQsyjW3h pic.twitter.com/Z8otKCf1I9

They are also rotating. Since the bearings are welded to each spoke, which is rotating as it oscillates, each bearing makes a full 360° rotation each time they travel from one end to the other and back again.

Each individual ball bearing moves ONLY is a straight line. https://t.co/6JfuIiE1A1
