From Amazon: BUY NOW Tippe-Tops
Precision Tippe-Top: spinning things often have surprising physics! This aluminum version of the famous flip-over top works better than any I’ve seen. Friction with the desk surface 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.

Heng Balance Lamp
Heng Balance Lamp: magnetic suspension sculpture and light- with two neodymium magnets on cords suspended by their mutual magnetic attraction. In this design by Zanwen Li, the bottom cord engages the light switch.
The Lollipopter
Many styles/colors to choose from:
From Amazon: BUY NOW: Lollipopter Kinetic Art
The Lollipopter (The Helicone): one of my favorite interactive kinetic sculpture designs. With a bit of practice one can master the transformation in both directions: A snap of the wrist imparts angular momentum to the "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. A creation by artist John Edmark.

Plasma Arc Lighter Physics
Get one here- but like any source of flame- use with caution!
From Amazon: BUY NOW Plasma Arc Lighter
Plasma Arc Lighter Physics: dual arcs of plasma exceed 1100 C (2000 F) on this flameless lighter. The breakdown voltage of air is about 3000 Volts per mm. Thus the circuit in the lighter must provide about 12,000 volts to produce this 4mm arc. The circuit is a simple one made possible by a transformer with very fine wire windings, a transistor, and a powerful lithium-ion battery (USB rechargeable). The circuit produces high frequency current oscillations in the coils that in turn produce the needed high voltage. Like having a Tesla coil in your pocket!
Vortex Dome

From PhysicsHack: BUY NOW: Vortex Dome Kalliroscope
Made with extraordinary craftsmanship and high quality materials, and sold at a very reasonable price!
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.

From Amazon: BUY NOW The Force Awakens Soundtrack + Holograms
Click on this link for another amazing work by Mr. Duke
Star Wars Specular Hologram on Vinyl: the two LP soundtrack from The Force Awakens featuring two amazing "scratch holograms" of a Tie fighter and the Millennium Falcon- the video barely captures the fullness of the 3D effect as the spaceships seem to hover above the surface of the record. These holograms were hand etched on the metal masters by artist Tristan Duke of Infinity Light Science. The etched grooves reflect a point source of light as sharp glints and the groves are arranged so that each eye sees a slightly different pattern such that, via stereopsis, the shiny points appear to float above or below the surface.

From engineDIY: BUY NOW: Mini Tesla Coil
The breakdown voltages of the elements featured in this post are described by Paschen's Law:
Here is a excellent article with an overview of the physics of glow discharge and its application in lighting and other technologies.
Gas Collection for Emission Spectra: pure samples of hydrogen, nitrogen and five noble gasses are subjected to the high frequency pulsed field of a miniature Tesla coil. Each gas has a characteristic breakdown voltage and emission spectrum- note that Nitrogen has the highest breakdown voltage and only glows when very near the coil where the field is most intense whereas Neon and Helium have the lowest breakdown voltage and begin to glow many centimeters away from the coil. The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element- the basis of spectroscopy. The Krypton tube also exhibits interesting oscillations with this particular Tesla coil.
The Galton Board
Available here:
From Amazon: BUY NOW
Galton Board
The Galton Board: 3000 steel balls fall through 12 levels of branching paths and always end up matching a bell curve distribution. Each ball has a 50/50 chance of following each branch such that the balls are distributed at the bottom by the mathematical binomial distribution. One of my favorite finds of 2018! An elegantly 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. In addition the number of balls in each bin can be predicted by Pascal's triangle (printed on the face over the pegs).
Magswitch
The smallest Magswitch in this product line, yet it can lift 17 lbs! The Magjig 60:

From eBay: BUY NOW Magswitch 60
Magswitch: switchable permanent magnet- a twist of a knob turns on a magnetic field strong enough to lift this 5.2 kilogram (11 pound) chunk of railroad rail. Magnetic fields, when combined, can be either additive or subtractive. This Magswitch model, the Magjig 60, works by aligning and counter-aligning two strong neodymium dipole magnets within a field channeling ferromagnetic casing.
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).

From movaglobes.com: BUY NOW Mova Globe: Jupiter
Jupiter Globe by Mova: rotating counterweighted globe sealed within a clear liquid filled acrylic sphere. The rotation is powered by light that shines through the semi-transparent Jupiter globe 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.
