From Amazon: BUY NOW Levitron Revolution 
From eBay: BUY NOW Levitron Maglev Platform 

Versions of the floating rings illusion can be found at the Exploratorium, at the Carnegie Science Center
and is also famously featured in the 1981 Superman movie: 
 

Levitron Revolution: well engineered control system uses an adjustable electromagnet and and a Hall effect sensor to levitate an 8cm diameter neodymium magnet platform 5 cm in mid-air. The feedback loop allows fine tuning of the magnetic field to exactly balance the pull of gravity. The platform also rotates, perfect for this floating rings illusion sculpture I constructed.

From engineDIY: BUY NOW Solar Levitating Motor (on all models here-remove brown protective film to reveal clear acrylic on rotor)

Mendocino Motor: each face of solar cell is connected to a coil of copper wire under the opposing solar cell. When the rotor is lit from above the top solar cell provides electric current to the coil in the bottom position which becomes a temporary electromagnet that pushes against the permanent magnet in the base propelling the rotor to rotate. As the rotor turns, the coil that moves into the bottom position is likewise energized by the solar cell currently at the top- one can say the light commutates this motor. 2D magnetic levitation is provided by permanent magnets where an acrylic plate constrains the third dimension, and makes for a nice bearing surface for minimal friction. Invented in the 1960s by Daryl Chapin of Bell Labs and popularized by Larry Springs of Mendocino CA 


Aqua Drop Puzzle

Three models/colors to choose from: 
From Amazon: BUY NOW Aqua Drop Puzzles 

From eBay: BUY NOW: Aqua Drop Puzzle

Aqua Drop Puzzle: a superhydrophobic coating allows this dexterity puzzle to use a drop of water as the "pinball". The white surface is a silica nano-coating that makes water roll off- a condition sometimes referred to as the Lotus effect because leaves of the Lotus plant have this property. 

Rheoscopic Planet 

Avalable in five colors! Get one here:

From Mr. Sci (Science Factory): Rheoscopic Planet

Rheoscopic Planet: this example of fluid flow kinetic art uses rheoscopic fluid encased in flexible bubble of plastic to reveal the intricate motion of turbulence. A suspension of tiny flat mica crystals tend to align themselves at the boundaries where the fluid is moving comparatively faster or slower, making the typically invisible flow patterns visible. Another unique science toy from @mrscisciencefactory

Aquarius Fountain Lamp

These fountains are individually made by the artist hence they are priced as art reflecting the labor involved: 
From Etsy store of Stephen Co : BUY NOW 
Aquarius Fountain Lamp

Aquarius Fountain Lamp: an oscillating stream of water is illuminated by strobe lights to reveal underlying structures and forms typically hidden from our vision. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the water stream appear to move upwards, change colors, and split into multiple braided streams. Art meets physics and clever technology in this wonderful creation by computer engineer Stephen Co. With sincere appreciation to Stephen @northerncircuits for sending me one of his hand crafted high tech fountains.
