Universe Sphere: 380000 laser etched dots, each dot representing a galaxy of stars, reveals the largest scale structure of our universe. This glass sphere contains a 3D mapping of galaxies in a volume of our universe spanning 800 million lightyears in diameter, and shows the clumping and distribution as seen by automated telescopic surveys such as that found in the Sloan Digital Sky Survey data. Hold a chunk of the universe in your hand!

From Amazon: BUY NOW DC Motors Kit
A DIY project to see if just shaking a bolt at the right frequency could make a standard nut rotate and fall off. Similar physics to the phase locking propeller toy featured in my last post. Motivated by videos seen on Instagram where a brass bolt is placed in magnetic putty and the nut mysteriously rotates up and off- now convinced that vibration is how that effect is produced. Here a small DC motor spins an offset mass to produce the vibrations.
I made this device from these components:
From Amazon: BUY NOW: heavy guage copper wire (for frame), inexpensive necklace chain (for connections), and hobby wire (to fasten chain to copper frames).
Check out these other Tensegity toys I've posted.
Tension Suspension: an interesting take on tensegrity where one heavy wire frame seems mysteriously suspended above another. This sculpture features strings (chains used here to make it look more dramatic) in tension equilibrium, with the top wire frame hanging from the bottom frame by the strand in the center, and the other three strands in tension to keep it from tipping over. This configuration is related to the concept of tensegrity invented by Kenneth Snelson and made famous by the architect Buckminster Fuller in 1949.

Impossible Arrow: an arrow made of wood through the center of standard steel hex nut. The arrow was carved and somehow placed through the nut- neither the wood nor the steel nut was cut or glued to produce this object. Not impossible, but creating this does depend on the use of some obscure physical properties of wood (similar to the impossible nail sculpture).

From Amazon: BUY NOW Mova Globes: all types
From Amazon: BUY NOW Mova Globes: Jupiter
From eBay: BUY NOW Mova Globes: all types
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.
These fountains are individually made by the artist hence they are priced as art reflecting the labor involved:
From Etsy store of Stephen Co : BUY NOW
Aquarius Fountain Lamp
Aquarius Fountain Lamp: an oscillating stream of water is illuminated by strobe lights to reveal underlying structures and forms typically hidden from our vision. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the water stream appear to move upwards, change colors, and split into multiple braided streams. Art meets physics and clever technology in this wonderful creation by computer engineer Stephen Co. With sincere appreciation to Stephen @northerncircuits for sending me one of his hand crafted high tech fountains.

From eBay: BUY NOW
From Amazon: BUY NOW
Time's Up: inverse of the sandglass- tiny plastic beads are less dense than the water and thus ascend to the top of the container under the influence of a buoyant force in accordance with Archimedes' principle. This timer takes almost exactly 6 minutes to complete shown here at normal speed for the first half of this video, and the second half is condensed to 24 seconds in time-lapse.
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 Aurora Plasma Designs: BUY NOW: Globes and Glow Wands
Click here for other amazing: Glow Discharge Designs
Tricolor Plasma Globe and Glow Wand: an engineered mix of low pressure noble gasses exhibit three colors of glow discharge in the plasma filaments that rise upward due to heating. A separate glass wand has a different gas mixture and phosphor coated beads that glow when in contact with the globe. A small high frequency coil at center creates the high voltage potential between the center electrode and the metal coated glass globe. Current flow through the thin gas produces the colorful emission spectra from the gasses.

Levitating Inq Lamp: Inq (the curious orange octopus) hangs illuminated and suspended by magnetic forces. I modified this lamp to incorporate the squish version of the @thecuriositybox mascot with a powerful neodymium magnet on top and a smaller magnet embedded with in Inq’s head- when the octopus is floating the bottom cord engages the light switch.
The amazing work of Emmanuel Péluchon can be purchased here:
From Boisselier.ca: BUY NOW: Fine Woodworked Rattleback
Inexpensive rattlebacks can be found here:
From STEMCell Science: BUY NOW: Rattlebacks
Woodwork Rattleback: prefers to spin counter clockwise- If spun clockwise, a complicated combination of friction, precession, and instability induced vibrations transforms the rotational energy into into rattling (energy of oscillations) and then into rotational energy in the opposite direction. This behavior is related to an asymmetry in weight along the left/right symmetry axis- the dark wood is Apple which has twice the density of the light colored Basswood(Linden). This asymmetry in weight induces an instability, quite like the vibrations that arise from an unbalanced tire, that transfers the rotational energy to the intermediate rocking vibrations. This beautiful physics toy was produced by Emmanuel Péluchon.

Hyperboloid Spinner: HypnoGizmo
Hyperboloid Spinner: the HypnoGizmo toy consists of a set of slanted straight nylon lines arranged to form the outline of a hyperboliod- the quadratic surface related to the revolution of hyperbola around its axis of symmetry. As the device rotates the beads slide along in succession on one of the straight paths leading to the complex visual display. So much fun math in this toy!

TV Rock: special crystalline form of the mineral gypsum acts as a natural fiber optic image conduit. Morocco seems to be the main source of this fibrous form, called satin spar gypsum, which exhibits pearl like luster and chatoyancy along two axes and transparency along the direction of the fibers. Not to be confused with ulexite, a mineral of boron with similar TV rock properties.
