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. 

Uplift 2.0

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. 

Slow Dance

This finally crated kinetic art piece avaiable here: 

From Wonder Machines: 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.


Earth Mass Black Hole with Space Warping Display Stand

Precision machined tungsten alloy spheres avaulable here:

From STEMCell Science: BUY NOW: Tungsten Black Hole Replica

Earth Mass Black Hole: this sphere of tungsten alloy has a diameter of 17.7mm, a precision representation of the size of the event horizon of a black hole with a mass equal to that of the Earth! If the entire mass of the earth could somehow be compressed to the size of this sphere, it would indeed collapse to a black hole with an event horizon defined by a Schwarzschild radius of 8.87mm. For comparison a black hole with the mass of the sun would be 6km across. This black hole replica is made of one of the densest materials available, a tungsten alloy with ρ=18.5 g/cm³ which produces a strange sensation when you hold it, with a weight of twice that of a ball bearing of equal size.
