Buda Ball: a spherical magnet is pinned 1.5 centimeters from the surface of its hardwood base. Within the base is an innovative 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- even when the base is in a vertical orientation! Amazing magnetic levitation physics demonstrated with aesthetic design (and very clever engineering) by the flyte.se team- the only (non-superconducting) system I know of that can suspend in a horizontal direction as shown in this video.

1790 Terrestrial Globe by Mova: rotating counterweighted globe sealed within a clear liquid filled acrylic sphere. The rotation in a Mova globe is powered by light that shines through the semi-transparent map image on to solar cells within the globe which drive a motor. But what does the motor push against to maintain the rotation? Believe it or not it uses magnets to push against the Earth's magnetic field like a compass needle. Wonderful physics of all kinds in the design of this clever device. The featured map is a faithful recreation of a globe famous for its accuracy at the time by Giovanni María Cassini and highlights the voyages of James Cook.

 


The Swinging Sticks

The Swinging Sticks Desktop Toy version from their website: 
From GeelongShop.com: BUY NOW The Swinging Sticks
 

The Swinging Sticks: a driven coupled chaotic physical pendulum as kinetic art where the placement of the rods' axes of rotation are engineered to exhibit the widest range of interesting motion. Four AA batteries and a simple electromagnetic kicker circuit in the base gives a tiny push to a magnet in the end of the large rod, keeping the system in motion for over a year! Perhaps one of the most famous physics toys out there as it was featured in the movie Iron Man II (sitting on the desk of Pepper Potts).

Bismuth Maglev Rod

Bismuth Maglev Rod: Small magnets are trapped, suspended and floating, within the notch of a rod cast from the diamagnetic metal bismuth. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the small floating magnet supplies the external field. Diamagnetic fields are pretty weak though, so a powerful neodymium magnet sits above the gap on the top of the rod, and its height is adjusted to help lift the small magnet against gravity. Another amazing creation by Ernie McElhannon of Element83.

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:

From Art of Play: BUY NOW: Story Clock

From FLYTE: BUY NOW: US & Global Sales Story Clock or in EU Story Clock

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!


Dual Axis Sand Pendulum

Available in many styles and colors: 
From Amazon: BUY NOW Sand Pendulum 
From eBay: BUY NOW Sand Pendulum  

Dual Axis Sand Pendulum: the kinetic energy trades back and forth between swinging toward the support arm and then swinging perpendicular to that path tracing Lissajous figures in the sand. The sand slowly dissipates the energy and the traced figures get smaller so the next one fits inside the last. Coupled oscillations like this can occur when multiple modes of motion (degrees of freedom) are available to the system.

The Dancing Helix

Get one here! Chose your color scheme and length, all come with the special motor and operating instructions:

From Educational Innovations: BUY NOW: Dancing Helix

The Dancing Helix: This kinetic mobile's mesmerizing motion arises from pulsed torsion waves that propagate up and down the length of a series of weighed rods connected by an elastic ribbon (which acts as a torsion spring). The waves arise by a special pulsed motor from which the strand hangs, and only spins for a second or so out of each minute. The twisting waves then constructively and deconstructively interfere creating an array of flowing motions.


Mini-Lollipopter

From eBay: BUY NOW: Lollipopter Kinetics

Mini-Lollipopter: new smaller cousin of one of my favorite interactive kinetic sculpture designs. A snap of the wrist imparts angular momentum to the "petals" which then rotate until an internal mechanism stops their motion with predetermined spacing- clockwise rotation transforms a helix to an abstract pine cone, counterclockwise returns the helix. Created by @john.edmark.

Slow Motion Timer

Get this device here:

From Amazon: BUY NOW: Paradox Silver Slow Motion Timer

Slow Motion Timer: instead of sand and air, dense oil and metal beads trade places in this unique timer. The small metal spheres slowly descend slightly tethered to each other due to the effects of viscosity as the fluid flows. This liquid timer is carefully constructed so there are no air bubbles to interrupt the delicate motion, and includes molded lens shaped windows on each side. Although more a piece of kinetic art, this particular timer consistently takes 4 minutes and 24 seconds to complete (partly shown here sped up x10).

Strandbeest Mini

From Etsy: BUY NOW: Hexacon and Sphericon Rollers

Hexacon Roller: beautiful 3D printed versions of a recent mathematical discovery of new developable rollers (objects that roll where every point on the roller’s surface comes into contact with the plane upon which it rolls). Similar to the sphericon (based on a square) the hexacon rolls in a straight line with a peculiar wobble motion but has a hexagonal cross section (swipe to see video loop of each in motion). The hexacon (2019) and sphericon (1980) are two of a family of such rollers called polycons discovered by David Hirsch, and described in a paper by Hirsch and Seaton published in January of this year. 

Gyro-Carousel

Get this unique toy and amny other whimsical spinnign tops from this store:

From Etsy: BUY NOW: Gyro-Carousel Globe Tops

Gyro-Carousel: two terrestrial globe spin tops of the same mass hang balanced on the ends of a beam such that their rotational motion is allowed to transfer to the system as a whole. The tops are set to spin as usual, but here small neodymium magnets are embedded in the tops of their stems which allows them to connect and hang from metal pins in the beam. The angular momentum of each top is slowly transferred to the rotation of the system by the slight force of friction acting at the attachment point on the beam produced by the stem of the spinning top. Studies show that approximately 1% of the original rotational kinetic energy of the tops is transferred to the rotating beam, not much- but enough to produce this interesting effect. A design by physicist Christian Ucke and a product of KreiselArt (Ulrich Büker).

This version is made of anodized aluminum and rotates via gearing and a motor powered by two AA batteries in the base. 

The Alchemist

Bismuth levitation available here: 
From Etsy- Element 83: BUY NOW Magnetic Levitation Sculptures 
featuring amazing Bismuth Crystals, Jewelry, and Maglev Kinetic Art

Circa 1981, Physicists transmute Bismuth to Gold: Particle accelerators make possible the ancient alchemist’s dream—but at a steep cost 

The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet levitates trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So modern nuclear physics, applied to the element Bismuth, finally accomplished the aspirations of the alchemists. ?Another amazing creation by Ernie McElhannon.
