Kinetic Traced Hyperboloid

This hard to find sculpture curretnly available here:

From Amazon: Hyperbolic Kinetic Sculpture

Kinetic Traced Hyperboloid: a straight rod glides through a symmetric pair of curved holes in this kinetic sculpture based on the hyperboloid, the 3D ruled surface traced by an offset revolved straight line. This version is made of anodized aluminum and rotates via gearing and a motor powered by two AA batteries in the base.

Wikipedia has an excellent introduction to the physics of Euler's Disk 

Eulers Disk: (best with sound on) this toy exhibits the motion of a “sprolling” coin, a motion that combines spinning and rolling. Designed with a large mass and very smooth edge, this device takes close to 3 minutes to come to rest- and amazingly, the contact point between the disk and the mirror can reach a speed of more that 200 mph! This video catches the first and last parts of this 2 minute and 42 second run, with two cuts to 240fps slow motion to show the curious motion. Watch the end with the sound on! 

Oloids: Solid and Anit-oloid

From KickStarter: ORDER NOW: Anti-Oloids in Brass, Copper, and Steel 

Beautiful solid oloids available right now here:

From the Matter Collection: BUY NOW: Oloids in Brass, Copper and Steel

Oloids: “solid hull” and “ruled surface” types made from brass and copper- oloids are unique solids that roll in such a way that every point on their surface comes in contact with the plane. The basis of the oliod’s geometry is that of two connected circles, one perpendicular to the other such that the rim of each circle goes through the center of the other. The shapes you see here are the results of connecting the rims of these circles together with a family of straight lines, one method leads to the solid convex hull form, and another way leads to the ruled oloid (anti-oloid). 


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. 

Sp!n Top

Get a Sp!n Top here- four colors to choose from:

From Art of Play: BUY NOW:  Sp!n Top

Sp!n Top: once set into motion the eye only perceives the punctuation mark ! in the center of a ring, with the vertical line seemingly suspended in space above the dot. The rate of spin is above the flicker fusion threshold of human vision, and the crossbars become blurred out and invisible- the effect is even more pronounced in person (hard to capture on video). Physics and psychophysics combine to produce this wonderful illusion!

The “Glorb” device design features a cylindrical cell with polarizing filters as the top and bottom windows and filled with this special rheoscopic fluid and a plastic bead. This assembly then slides into a base with white LEDs to supply backlighting. Many thanks to Laminar Sciences Corp for supplying this beautiful display cell and bottles of KaleidoFlow fluid for experimentation.


Vortex Dome

Get one from David Fowler's Etsy shop: 
From PhysicsHack: BUY NOW: Vortex Dome Kalliroscope 
Made with extraordinary craftsmanship and high quality materials, and sold at a very reasonable price! 

Vortex Dome Kalliroscope: kinetic art with rheoscopic fluid in a rotating base. Visualizing the invisible- the Vortex Dome is the creation of engineer/inventor and @physicsfun featured artist David Fowler aka @physicshack who creates this modern rotating kalliroscope that generates complex and beautiful structures similar to those seen in the cloud bands of the gas giants of our solar system like Jupiter. The capsule is constructed of high quality glass on a heavy stainless steel base which glides on bearings for long spin times. 

The Lollipopter

Four styles to choose from: 
From Amazon: BUY NOW: Lollipopter Kinetic Art 

The Lollipopter (The Helicone): one of my favorite interactive kinetic sculpture designs. With a bit of practice one can master the transformation in both directions: A snap of the wrist imparts angular momentum to the "petals" which then rotate until an internal mechanism stops their motion with predetermined spacing- a helix transforms to an abstract pine cone. A second snap of the wrist in the opposite direction returns the helix. A creation by artist John Edmark.

Sean Agustine March

Fresnel Minor Lamp: Microlayers of metals and metal oxides allow a slab of glass to transmit a different color than it reflects through thin-film optical phenomena such as interference and selective absorption. In this remarkable art piece, dichroic glass is combined with infinity mirror type multiple reflections creating this dazzling display of physics! Special thanks to @seanaugustinemarch for this amazing addition to my collection.

Orbit Spinning Top

Get this 3D printed top here:

From Etsy: BUY NOW: Orbit Spinning Top

Orbit Spinning Top: asymmetric in shape but perfectly balanced about the rotation axis, this beautiful stainless steel 3D printed top will spin for a couple minutes. As the top slows down interesting aliasing arises as the angular velocity changes with respect to the frame rate of the camera. 

Slow Dance

This finally crated kinetic art piece avaiable here: 

From Wonder Machines: BUY NOW: Slow Dance

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.


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! 

Holiday Pyramid

Many types and themes available: 
From Amazon: BUY NOW Christmas Pyramids 
From eBay: BUY NOW Christmas Pyramid

Holiday Pyramid: a simple heat engine- rotational motion resulting from the convection of hot air due to the candle flames of two tea lights. These holiday decorations come from a German Christmas tradition, Weihnachtspyramide, that dates back more than 200 years! Energy transfer: chemical bonds to heat to kinetic energy of the rising air to rotational kinetic energy of the turbine and reindeer. 

EDC Gyroscope

Precision machined stainless steel gyroscopic spinners avaialbe here:

From mechforce.com: BUY NOW: EDC Gyroscope

EDC Gyroscope: a metal rotator spins freely within a gimbal arrangement and features precision bearings used throughout (1 ball bearing in core plus 4 micro-bearings in the intermediate ring). Spin up the center gyro and conservation of angular momentum will keep its axis of rotation pointing in a constant direction even as the outer rings are rotated to and fro. Precision machined from stainless steel- the ultimate spinner!

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! 

Shashibo Geometric Art

ORDER HERE : Shashibo Geometric Art

Shashibo Geometric Art: dissect a cube into 12 equal irregular tetrahedra, connect these pieces symmetrically with hinges, and add 36 magnets to create a device with more that 70 geometrically interesting and aesthetic configurations- a few are shown here. With practice the various transitions can flow very smoothly- this video are some of my initial explorations with this unique puzzle. 

The ΦTop

Professor Brecher has a limited supply of these "golden" (brass) versions of this top available on Etsy 
From Etsy: BUY NOW PhiTOP in Brass 

The ΦTop - Golden Version: spinning things have surprising physics! This unique top is made of solid brass in the shape of a prolate elIipsoid- and the name of the top is derived from the following design requirement: the ratio of the semi minor (short) axis to the semi major (long) axis is made equal to the mathematical constant the golden ratio φ (phi). Invented by astrophysicist Kenneth Brecher, 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 and the glass surface has minimal friction allowing the top to spin for a long time- this video shows various stages of 8 minutes of total spin time.
