Arch Balance Toy

Get this elegant toy here:

From Ludu Ludi in Spain: Nivana Balance Toy

Arch Balance Toy: this elegant sculpture toy seemingly defies gravity- a careful placement of the pendulum will locate the center of mass of the arch + pendulum system directly above the 1cm wide foot of the arch, creating a state of unstable equilibrium. No magnets used or needed for this physics! Hang and balance your favorite object from this arch. Made in Spain by Pico Pao, the Nirvana balance toy come with an old fashioned throwing top as the pendulum bob.

STORY Clock

This very high-tech clock is also high end (more expensive than most items I feature), with excellent craftmaship and technology that is clearly hard to replicate so that it is only made by, and available from, the FLYTE team:

STORY Clock: a spherical magnet hovers one centimeter from the face of this amazing clock and orbits in a circle to indicate the time- for this video I selected an orbit period of 40 seconds to show off the motion. The orbit of the magnetic ball can be set to any period but also has default selectable presets to indicate the current hour, minute, or second. This kind of levitation uses a control system with adjustable electromagnet coils in a feedback loop with Hall effect sensors which allow for fine tuning of a magnetic field to precisely balance the pull of gravity. Amazing magnetic levitation physics demonstrated by clever engineering by the @flyte.se team, this clock will work lying flat or hung on a wall vertically!

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

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.
