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!

MezmoCoin 

Mezmoglobe: precision machined kinetic desk toy with helical motion illusion. Give this metal sphere a spin and the imparted angular momentum (along with precision bearings) allows for sustained rotation. The spiral design converts rotational motion to translational motion, and imparts the illusion that fluid like ripples are traveling along the metal surface. Another intriguing design by Kristoph Krisjans.

Kostick Stars: The geometric forms of these kinetic sculptures snap into place due only to the balanced tension forces between thear slightly bent bronze wires. The large star is comprised of six struts, each made of 5 wires, which are made to intersect and weave though each other with beautiful geometric regularity. Similarly the small star has 4 struts each made of 3 wires. The ends of the 6 struts of the large star become the 12 vertices of an icosahedron, and the ends of the 4 struts of the small star point to the 8 corners of a cube. Both stars can be collapsed along many of the symmetry axes. Invented and patented in 1970, these stars are still produced and sold by artist and designer John Kostick.

The Helicone

The Helicone: an interactive kinetic sculpture designed by @john.edmark and distributed by playableArt. With a bit of practice I finally mastered the transformation in both directions: A snap of the wrist imparts angular momentum to the laser cut wood 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.

LessMore Bowls: (non-physics post) these serving dishes by @artofplay are a 3D version of the famous Jastrow Illusion, where the lower curve always appears larger than the top one. Note that even after we verify the bowls are the same size, our perception still misleads- a reminder that we need science to transcend the limits of our senses.

Check out my short blog post on the history and physics of the Tippe-Top 

Fine Wood Tippe-Top: spinning things often have surprising physics! This lathe worked version of the famous flip-over top is made of ebony and wood from the pink ivory tree. Friction with the mirror provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position.

Strobe Coin

Strobe Coin Spinning Top: beautiful coin tops made of solid copper and silver display a remarkable spinning strobe pattern when viewed on video from a smartphone. Incredible art/physics from @shirepostmint that takes advantage of aliasing and the wagon-wheel effect. The black enamel pattern on the top of the coin is specifically designed to interact with the frame rate of the video process to produce the intricate motions of the concentric circle patterns seen here, and on the back of the coin a starburst pattern provides similarly interesting effects. These coins can be spun on both sides with spin times reaching 12 minutes! The contact points are super hard spheres of silicon nitride black ceramic (Si3N4) providing a low friction bearing.

The Toroflux


Why does it look like a bubble when moving fast? Wikipedia has the details: when the object exceeds a certain speed the flicker fusion frequency of our vision produces the bubble illusion. 

The physics of the toroflux is wonderfully illustrated and explained in this article by Daniel Walsh. 

Toroflux: kinetic art toy made from a single continuous loop of stainless steel band. The band of spring metal is woven such that it forms a torus that can clamp on to and roll down a stick, segment of tubing, or even an arm. Amazing combination of math and kinetic art invented by Jochen Valett.

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.
