From Art of Play: BUY NOW: Slow Dance
Slow Dance: a kinetic sculpture via induced vibration and high speed strobe lighting in which objects exhibit subtle and beautiful motion when mounted within this special frame. I love how the electromagnet, with its beautiful copper windings, is prominently featured at the bottom of the frame. Electronics within the frame send AC currents to the electromagnet which then pushes and pulls magnets on each side. These magnets are affixed to leaf springs to which feathers, flowers, and other objects are attached with elastic bands. The arrangement is then illuminated by LEDs set to strobe at just the right frequency to produce the slow dance illusion.

From KiwiCo: LEARN MORE: Tinker Crate Subscription
Glow Trace Chaotic Pendulum: this fun and DIY kit features a UV diode to trace the intricate path of this double pendulum system on to a phosphorescent screen, revealing the physics of chaotic motion. It’s amazing that such complex motion can arise from a simple assembly of two pendulums, one attached to the end of the other. Chaotic motion, such as that observed here, is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time.
Own this scuplture by Ivan Black (made in collaboration with Italian manufacture house Atellani):
From Art of Play: BUY NOW Square Wave
The Square Wave: an interactive kinetic sculpture of 24 interlocking right angle metal rods from the mind of artist Ivan Black. Waves propagate, folding the structure into a tight curl- and a reverse snap will bring it back to the initial flat square state. An important design feature is that each right angle rod is limited to move through about 45 degrees, and all through parallel axes, allowing for the beautiful rotational wave motion via a cascade of angular momentum transfer.
Five animations to choose from- collect them all!

From Educational Innovations: BUY NOW: Dancing Helix
The Dancing Helix: This kinetic mobile's mesmerizing motion arises from pulsed torsion waves that propagate up and down the length of a series of weighed rods connected by an elastic ribbon (which acts as a torsion spring). The waves arise by a special pulsed motor from which the strand hangs, and only spins for a second or so out of each minute. The twisting waves then constructively and deconstructively interfere creating an array of flowing motions.
Get the full version (8 disks made of wood) or the mini (6 disks, blue or red plastic):
From Amazon: BUY NOW TrueBalance Coordination Puzzle
TrueBalance: coordination challenge puzzle- get the six disks, connected by bearing swivels, into a vertical stack by only tilting the handle. Harder than it looks to get each disk’s center of mass above the one below at the same time into the unstable equilibrium final state. The swivels constrain the system, limiting the degrees of freedom, and allowing strange and interesting motion. Kinetic art as a toy!

From Etsy- Element 83: BUY NOW Magnetic Levitation Sculptures
featuring amazing Bismuth Crystals, Jewelry, and Maglev Kinetic Art
Circa 1981, Physicists transmute Bismuth to Gold: Particle accelerators make possible the ancient alchemist’s dream—but at a steep cost
The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet levitates trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So modern nuclear physics, applied to the element Bismuth, finally accomplished the aspirations of the alchemists. ?Another amazing creation by Ernie McElhannon.
From Rail and Oak: the Esty shop of Logan Needham
From Etsy: BUY NOW Planetary Gear System
Planetary Gear Train: with non-circular gears! This piece of kinetic art features a 6-sided Sun Gear, six 3-sided Planetary Gears, all held within the 12-sided space of the Annular Gear. The video captures three of the many interesting modes of these epicylic gear systems: 1) holding the sun gear fixed while rotating the annular gear allows the planetary gears to orbit, 2) pinning the planetary gears such that they can spin (but not orbit) allows the sun gear to go in the reverse direction of the annular gear, 3) holding one planetary gear fixed produces curious motion- note that although the other planetary gears move they do not spin about their axes! Situation 2) is how reverse gear is accomplished in the transmissions of many vehicles. Thanks to Logan Needham (@pillagethenburn) for the ingenuous display stand that allows full demonstration of this work of physics and engineering art.

From Amazon: BUY NOW Toroflux
Get one and flow with it!
From Art of Play: BUY NOW
Why does it look like a bubble when moving fast? Wikipedia has the details: when the object exceeds a certain speed the flicker fusion frequency of our vision produces the bubble illusion.
The physics of the toroflux is wonderfully illustrated and explained in this article by Daniel Walsh.
Mini-Toroflux: kinetic art toy made from a single continuous loop of stainless steel band. The band of spring metal is woven such that it forms a torus that can clamp on to and roll down a stick or in this case s segment of cord. This miniature version loops through itself nine times which requires the spring ribbon to twist creating a tension such that when released the spring will pop into its minimum energy state- a flower-like torus. Amazing combination of math and kinetic art invented by Jochen Valett. Thanks to Tim Rowett for sending me this rare mini version for my collection.
Available for all the planets and several versions of Earth:

From eBay: BUY NOW Mova Globe: Jupiter
Jupiter Globe by Mova: rotating counterweighted globe sealed within a clear liquid filled acrylic sphere. The rotation is powered by light that shines through the semi-transparent Jupiter globe on to solar cells within the globe which drive a motor. But what does the motor push against to maintain the rotation? Believe it or not it uses magnets to push against the Earth's magnetic field like a compass needle. Wonderful physics of all kinds in the design of this clever device.
