From Amazon: Buda Ball
See also: The Story Clock
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.
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).
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!
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.

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.
From Amazon: BUY NOW: Lollipopter Kinetics
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.

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).

From Amazon: BUY NOW Strandbeest Model Kit
Read about Theo Jansen and his novel leg linkage mechanism for the Strandbeests via these Wiki pages.
Strandbeest Mini: A fully working model of artist Theo Jansen's Strandbeest kinetic sculpture which features Jansen's linkage- a unique leg mechanism which converts rotary motion of a crackshaft into smooth walking motion. Jansen's creations are usually a couple meters high and walk the beaches of the Netherlands powered by the wind. This version comes as a model kit that snaps together with no glue- a really fun project!

Vortex Dome Kalliroscope: kinetic art with rheoscopic fluid in a rotating base. Visualizing the invisible- the Vortex Dome is the creation of engineer/inventor and @physicsfun featured artist David Fowler aka @physicshack who creates this modern rotating kalliroscope that generates complex and beautiful structures similar to those seen in the cloud bands of the gas giants of our solar system like Jupiter. The capsule is constructed of high quality glass on a heavy stainless steel base which glides upon an included bearing set for long spin times.
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).

Galton Board version available here:
From Amazon: BUY NOW
The Random Walker: second model of two Galton Boards designed and produced by IFA.com- this version is made to demonstrate probability in investment returns of a global stock market portfolio relating to risk capacity. Slow motion reveals the erratic path of each steel ball (second half of video). The red graph shows the distribution of 592 monthly returns (mean =1%, SD=5%) representing data from 50 years of an IFA Index fund- here the random “walk” of 3000 steel balls falling through 12 levels of branching paths always produce a close match, and both distributions tend toward the famous bell curve distribution. A wonderfully designed modern version of the Galton Box invented by Sir Francis Galton(1894) to demonstrate the Central Limit Theorem - showing how random processes gather around the mean.

From Etsy: BUY NOW: The DeltaCELT
The DeltaCELT: a new rattleback design where the indentations create an asymmetry in the distribution of mass that leads to rotation reversals when spun: 1) If spun clockwise, after about two full rotations, a complicated combination of friction, precession, and instability induced vibrations transforms the rotational energy into into end-to-end rattling (energy of oscillations) and then into rotational energy in the opposite direction. 2) If spun counter-clockwise, after about 30 full rotations the rotational energy translates into side-to-side oscillations leading to a clockwise reversal (swipe to see- less dramatic but still amazing). The design is made of solid brass and has the shape of a bisected prolate ellipsoid in the proportion of the mathematical constant δ =4.669.. (Feigenbaum dynamical constant) giving the name to this new design by astrophysicist Kenneth Brecher. The DeltaCELT comes with the polished slate spinning surface for optimal performance.

From KiwiCo: LEARN MORE: Tinker Crate Subscription
Glow Trace Chaotic Pendulum: this fun and amazing DIY kit features a UV diode to trace the intricate path of this double pendulum system on to a phosphorescent screen, revealing the physics of chaotic motion. It’s amazing that such complex motion can arise from a simple assembly of two pendulums, one attached to the end of the other. Chaotic motion, such as that observed here, is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time.

From Amazon: BUY NOW: Square Wave Horizon
See also: The Square Wave (Original)
Square Wave Horizon: a second incarnation of Ivan Black’s Square Wave interactive kinetic sculpture- in this version 20 interlocking right angle metal rods are mounted horizontally with accompanying base and grips at each end which allows one to rotate the structure to and fro. Waves propagate, folding the structure into a tight curl- and a reverse snap will bring it back to the initial flat square state. An important design feature is that each right angle rod is limited to move through about 45 degrees, and all through parallel axes, allowing for the beautiful rotational wave motion via a cascade of angular momentum transfer.
Available on Etsy: BUY NOW Motion Ferrofluid Sculpture
Colored Ferrofluid Display Cells: spectacular metallic blue, gold, and black display cells by czferro - colloidal ferromagnetic liquids in a specially prepared water-alcohol suspension. Curious behavior results from the interplay between magnetic force and surface tension. The gold and blue coloring appears to be from a thin coating at the boundary between the ferrofluid and the suspension liquid. Still exploring the details of the coloring and the specific makeup of the clear suspension fluid - both trade secrets it seems.
