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

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. 


Gifeez: Modern Phenakistiscope

This amazing toy for under $10: 

From Amazon: BUY NOW: Gifeez Animation Toy

Gifeez: a modern zoetrope type device with built in strobe light to explore the physics and psychophysics of motion animation- still images flashed in rapid succession produces the illusion of motion through persistence of vision. This inexpensive device has two modes: 1) the strobe frequency is set to various ratios of the spin frequency creating fascinating motion of abstract geometrical images, and 2) the strobe is set to animate simple cartoons. When the image flash rate is above the flicker fusion frequency (approximately 16Hz) we perceive fluid motion- the basis for all movies and TV. This device includes a centripetal switch that turns on the strobe and a motor that keeps the disk spinning for a couple minutes and comes with 15 printed double sided disks and a few blanks to allow for your own designs.

Click here for more on the PhiTOP and using magnetic induction to spin it up. 

Tesla’s Egg of Columbus: a copper ellipsoid egg (PhiTOP) mysteriously spins and stands upright in this modern version of Tesla’s famous demonstration from the 1893 World’s Fair in Chicago that first showcased the principles behind wireless power transfer and his AC induction motor. Rotating magnetic fields from under the wooden platform induce electric eddy currents to flow in the copper PhiTOP- these currents then create their own magnetic field which oppose the initial fields underneath and pushes the PhiTOP to spin. This version differs from Tesla’s in that the rotating magnetic fields are created by, well, a pair of rotating neodymium magnets (revealed by lifting the top platform in this model). Credit to astrophysicist Kenneth Brecher, the creator of the PhiTOP, and this unique means of using a common lab magnetic stirrer to create the induced currents. Finally, the ellipsoid top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top. 

The Swinging Sticks

From GeelongShop.com: BUY NOW The Swinging Sticks
 

The Swinging Sticks Desktop Toy: a personal favorite, this kinetic art device is the ultimate physics toy, and was featured in the movie Iron Man II (sitting on the desk of Pepper Potts). The physics magic of this device displays the essence of chaotic motion with coupled pendulums- the placement of the rods' axes of rotation are engineered to exhibit the widest range of interesting motion. Four AA batteries and a simple kicker circuit in the base gives a push to a magnet in the end of the large rod keeping the system in motion for over a year! 


Pisces Kinetic Art Lamp

The Pisces Lamp is now accepting pledges on Kickstarter. 

On KickStarter: PLEDGE NOW: Pisces Kinetic Art Lamp

This campaing come form the same artist who created the successful campaing for rhe Aquarius Fountian Lamp

Pisces Kinetic Art Lamp: standing waves of a rotating string are illuminated by strobing light in this new kinetic sculpture by artist and computer engineer Stephen Co. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the rotating string change colors, merge into spoon shaped surfaces, or split into multiple braids. The string is propelled by small motors and the standing waves can have multiple nodes, which can be altered by touching the string while in motion.

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. 

Zoetrope

Get this inexpensive version here- comes with many animations and balnk strips tomake your own:

From Amazon: BUY NOW: Zoetrope 

Zoetrope: the physics and psychophysics of motion animation- still images flashed in rapid succession produces the illusion of motion through persistence of vision. The slits are crucial to creating the illusion by blacking out the visual stimulus for a short duration- without these pauses only a blur is perceived. When the image flash rate is above the flicker fusion frequency (approximately 16Hz) we perceive fluid motion- the basis for all movies and TV. 


Reuleaux Rotor

This toy is availble from Amazon Japan and will ship to the US:

From Amazon.jp: BUY NOW: Reuleaux Rotor Wodden Toy

Reuleaux Rotor: this famous curve of constant width, the Reuleaux triangle, can rotate such that at all times it remains in contact with all four sides of a square. As demonstrated by this wooden toy from Japan, the rotor covers approximately 98.77% of the area of the square, missing only the sharp corners. The curves in the corners are in the shape of an elliptical arc. Fun fact: a Reuleaux triangle has a perimeter equal to pi times its width- just like a circle!

Special thanks to @seanaugustinemarch for this amazing addition to my collection.

Rolling Ball Fountain

Find this and similar fountains here:

From Amazon: BUY NOW: Rolling Ball Fountain

Rolling Ball Fountain: this miniature kugel fountain features a glass sphere that sits on a socket of precisely similar shape, and is suspended on a very thin (less than half a mm) film of moving water which greatly reduces friction. The velocity of the water in the thin layer slows as it spreads out via a hole in the socket, and this hole is offset from the center so that the interaction with the water stream sets the ball spinning. A small pump provides the flow rate, and colorful LEDs illuminate the glass sphere to show off the rotation. Perhaps you’ve seen public art installations featuring giant granite spheres weighing tons and yet similarly suspended on a thin layer of flowing water. Physics principles involved here include viscosity and Reynold’s number, the Navier-Stokes equation, Bernoulli’s principle and the study of thin layer lubricants.
