Luna Kinetic Illusion: precision machined and crafted kinetic desk toy with helical motion illusion. A metal sphere seemingly defies gravity as a coil spins around it in this astonishing design by Kristoph Krisjans and the @mezmoglobe team. Currently taking pledges on Kickstarter where they have had nineteen successful campaigns. ➡️ Follow the link in my profile for info on where to get this device and other amazing items featured here in @physicsfun #physics #mezmoglobe #vortex #spiral #kinetic

Spiranetics Kinetic Toy: a rotor rolls while magnetically connected to a helical track in this toy sold by The Nature Company in the 1990s. The clever geometry allows , with the right timing, the rotor speed can be ramped up by just rotating the helix in place- or to get it to higher rotation speeds the helix can come out of the base as demonstrated. This device is a fancy version of the Whee-Lo type toys- with physics of angular momentum, magnets, and combinations of rotational and translationa
