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 Art fo Play: BUY NOW: Dot Animation Cards
Dot Animation Cards: a unique version of barrier-grid (kinegram) animation where a matrix of holes allows only some of the dots on the covered card to show in succession producing the appearance of motion. In this clever design rotating the card with dots by 180 degrees reveals a second animation. Affordable kinetic art by Shigeki Naito that plays on the psychophysics of vision.
Available here in a variety of colors and wood types:
From Amazon: BUY NOW: Kwish Tensegrity Toy
Tensegrity Icosahedron Toy: an architectural engineering inspired toy for tots- believe it or not this design is sold as a toy for babies: the Skwish rattle by the Manhattan Toy Company. Six wood struts float isolated from each other but held in a stable configuration by a net of 24 connecting elastic cords. This configuration of three sets of parallel struts forms a Jessen’s icosahedron under tension, and was invented by the famous architect Buckminster Fuller in 1949. A physics toy for ages 0 and up!

MaBoRun Mini: interplay of potential energy of gravity and conservation of angular momentum- a simulation of decaying orbits as the marbles whirl down the funnel shaped tracks. A battery powered conveyor brings the marbles back to the top.

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!
CineSpinner: motion animation from Moiré pattern effects of constructive and deconstructive interference. Affordable kinetic art by Scanimation creator, artist, and author Rufus Butler Seder.

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 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.

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.

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.

olling Marble Sculpture: marbles perform gymnastics as potential energy of gravity is converted to kinetic energy. An elegantly designed auger conveyor, an Archimedes' Screw, brings the marbles back to the top (powered by an AA battery and a small motor). Conservation of angular momentum produces a simulation of decaying orbits as the marbles whirl down the the main funnel shaped feature.
Sphericon and Hexa-sphericon: order your set today!
From the Matter Collection: BUY NOW The Sphericon (Hex and Regular)
Hexa-Sphericon: Sphericons are unique solids that roll in such a way that every point on their surface comes in contact with the plane. Solids from the sphericon family all have one side and two edges. Each sphericon is based on a regular polygon, with the basic sphericon derived from a square, and here- a more interesting case with more complex rolling motion- from a hexagon.
