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.

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.
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!
Available in many styles and colors:
From Amazon: BUY NOW Sand Pendulum
From eBay: BUY NOW Sand Pendulum
Dual Axis Sand Pendulum: the kinetic energy trades back and forth between swinging toward the support arm and then swinging perpendicular to that path tracing Lissajous figures in the sand. The sand slowly dissipates the energy and the traced figures get smaller so the next one fits inside the last. Coupled oscillations like this can occur when multiple modes of motion (degrees of freedom) are available to the system.

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.
This amazing device now available here:
From ArtofPlay: BUY NOW: Uplift 2.0
Uplift 2.0: light powered kinetic sculpture with mesmerizing apparent translational motion due to rotation of a spiral element under glass and mounted on precision bearings. The rotation is propelled silently by a simple and elegant bidirectional motor- a disk shaped copper coil which interacts with an array of six neodymium magnets and powered by a single solar cell. The included hand held magnet allows one to select the direction of flow. A stunning creation for any windowsill by artist and inventor Tom Lawton.

From Amazon: BUY NOW: Square Wave Horizon
See also: The Square Wave (Original)
Square Wave Horizon: a second incarnation of Ivan Black’s Square Wave interactive kinetic sculpture- in this version 20 interlocking right angle metal rods are mounted horizontally with accompanying base and grips at each end which allows one to rotate the structure to and fro. 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.

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.

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.

Strobe Coin Spinning Top: beautiful coin tops made of solid copper and silver display a remarkable spinning strobe pattern when viewed on video from a smartphone. Incredible art/physics from @shirepostmint that takes advantage of aliasing and the wagon-wheel effect. The black enamel pattern on the top of the coin is specifically designed to interact with the frame rate of the video process to produce the intricate motions of the concentric circle patterns seen here, and on the back of the coin a starburst pattern provides similarly interesting effects. These coins can be spun on both sides with spin times reaching 12 minutes! The contact points are super hard spheres of silicon nitride black ceramic (Si3N4) providing a low friction bearing.

From Etsy: BUY NOW Kyle's Kinetics
Surf's Up!: Another gravity defying creation by Kyle Auga, this time a well-balanced stainless steel surfer that carves waves in the air for over 10 minutes on one push! The surfer has the curious motion of a 3D physical pendulum- a complex motion which can be broken down into oscillations along two dimensions and rotation about the point of contact. The stick figure plus counterweights and bar structure is designed such that its center of mass is few centimeters below the contact point when at rest. When the sculpture is tipped the center of mass swings under the pivot point in this stable equilibrium condition- no magnets needed to create this physics magic.
