Click here for similar itmes: Zoetropes
eyeMo Linear Zoetrope: the physics and psychophysics of motion animation- still images flashed in rapid succession produce the illusion of motion through persistence of vision. This unique version uses an array of lenses, and the images are flashed one by one as the series of lenses moves past the eye. When the image flash rate is above the flicker fusion frequency (approximately 16Hz) we perceive fluid motion- the basis for all movies and TV.
Sometimes available on eBay, and similar mirror illusion banks:
From eBay: BUY NOW: Mirror Illusion Bank
Mirror Illusion Spacecraft Bank: Symmetry + Reflection = Illusion. Deposit a coin (which seems to vanish) and a spacecraft of some sort states to revolve within a silver ring seemingly suspended in space. The symmetry of the ring and craft allows a half of these objects to appear as a whole, and a AA battery powers a motor which drives gears to slowly spin the portion of the mirror inside the ring (with the spacecraft attached). The best version of the mirror illusion box I’ve seen.
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.

Tannenbaum Marble Run: tree shaped kinetic marble toy cleverly constructed from a single piece of bent rod. Season’s Greetings to all on Instagram!
Choose from black, blue, or gold ferrofluid:
Available on Etsy: BUY NOW Nano Tree Ferrofluid Sculpture
Ferrofluid Magnetic Tree Sculpture: the 'Nano Tree' by Concept Zero designs using gold colored ferrofluid which can be manipulated with a handheld magnet. The spiky structure is due to the balance between the forces from the focused magnetic fields (from a neodymium magnet in the base connected to an iron rich bolt) and the forces from liquid surface tension on the colloidal ferromagnetic liquid.
Well engineered brass spinning toys by SiriusEnigmas
From Etsy: BUY NOW: The PiTOP
From Etsy: BUY NOW: The PhiTOP
The PiTOP: this beautiful brass cylinder has a radius of 1 inch, a height of 1/π inches, and displays the first 109 digits of π on its face. Spin this disk (best with sound on) and it will demonstrate some very interesting physics involving energy transfer and conservation of angular momentum. The edges of the cylinder are rounded and engineered to exhibit an optimum motion of a “spolling” coin, a motion that combines spinning and rolling (closeup shown in 240fps). As the disk’s angle of inclination decreases the speed of the rolling increases dramatically until the contact point with the mirror is moving in excess of 200mph. From the mind of physicist Ken Brecher, inventor of the PhiTOP (swipe for video). Note also that with the specified height, that the volume of this cylinder is exactly 1 cubic inch!
These are mostly available in the Demark Hoptimist shop, but can be ordered internationally here:
From Amazon.uk: BUY NOW: Hoptimist Giraffes Art Toy
Coupled Oscillator Giraffes: set one giraffe into motion and the others will join, trading the kinetic energy between each other in an intricate dance. Three identical leaf springs comprise the necks, and the eyes of each giraffe are neodymium magnets. The magnetic repulsion between the heads allows each giraffe to slightly influence its neighbors, hence these oscillating springs are coupled via this magnetic influence which leads to complex patterns of energy transfer with each taking a turn to stand still while the others move dramatically. From the Danish toy maker Ehrenreich (Hoptimist) originally produced in 1972 and recently reissued in the form seen here.
Get a similar affordable Zoetrope from these sources:
From Etsy: BUY NOW: Zoetrope
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.

From Etsy: BUY NOW: 3D Printed Marble Runs
See more (miniture) marble runs here: Marble Run Fun
Rolling 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.
Get this chaotic fidget spinner here:
From Amazon: BUY NOW: Triple Pendulum Spinner
Triple Pendulum Chaotic Fidget: This interesting spinner is made from stainless steel and features three physical pendulums each mounted with their own low friction bearing. In slow motion one can see the kinetic energy and angular momentum is transferred from one pendulum to another as the entire device rotates, with some spinning rapidly and others rotationally at rest- the intricacies chaotic motion, characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time.
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!
Get this and other beautifully crafted math themed tops here:
Fropm Etsy: BUY NOW: The eTOP
The eTOP: an ellipsoid based on the famous Euler’s constant e, diameter 2” and thickness 2/e”- spinning magnets from the magnetic stirrer induce electric currents to flow in the copper eTOP- these currents then create their own magnetic field which opposes the magnets underneath and pushes the eTOP to spin, producing interesting motion and sound. Credit to astrophysicist Kenneth Brecher, the creator of the eTOP, PhiTOP, and this unique means of using Lenz’s Law to spin it up. This top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top. The concave mirror keeps the top from wandering off of magnetic stirrer.
Sold individually, or as a set, here:
From Etsy: BUY NOW: Plasma Glassware and Excitation Base
Neon Plasma Glassware: serve up a platter of plasma! These double walled glass mugs glow orange and blue from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer (Tesla coil) that generates high voltage electric fields (but at very low current) which excites the neon to glow, and also serves as a display platter. The inner volume of each glass varies in thickness which leads to variations in heat and pressure which in turn produces different excitations (orange and blue) of the neon gas in patterns that dance and dazzle the eye. An upcoming video will show these filled with beverages. Stunningly beautiful kinetic art and tech by creator Zerg Dragonymous.
Get this particular sand kinetic art here:
From Amazon: BUY NOW: Sandscape Kinetic Desk Toy
Click here for more amazing types of kinetic sand art.
Sandscape Spontaneous Stratification: a striking feature of this sand motion desk toy is the formation of striped layers. Typically pouring stuff together results in further mixing, yet here, when the sand mixture descends through a gap, the resulting pile is ordered into sorted layers. The larger rounded dark grains separate from the smaller sharp-edged white grains forming the layers you see here. The darker grains alone would stack into a steeper pile (larger angle of repose) than the white which would form a less steep pile.
