From eBay: BUY NOW Star Wars Mickey Ears

Mickey Mouse Physics: the Millennium Falcon battles TIE fighters in a three panel animation printed on layers of optical acrylic. Red, green, and blue LEDs switch on and off lighting the layers sequentially in a loop producing the animated scene from Star Wars. Light from the LED attached to a specific layer undergoes multiple internal reflections as it passes through the clear plastic illuminating mostly that layer- the same principle employed in fiber optic cables. Disney + Lucasfilm = mouse ears of the future!

Viscous Flow Resin Lamp: art from mixing high viscosity fluids. Each lamp from EP Designlab captures a unique pattern based on the physics of nondiffusive turbulence resulting from the mixing of viscous fluids- in this case silicone resins. When the resins cure the pattern is captured and frozen in place- and these blocks are ready to display with USB rechargeable LED illumination in the base. With this process no two lamps are alike, and all capture intricate mixing physics.

The Levimoon

Get a levitating moon globe lamp here! 
FromAmazon: BUY NOW Levitating Moon Globe Lamp

The Levimoon: this detailed moon globe is an adjustable lamp that levitates! Charged through wireless induction via the base, the moon floats above the Earth while illuminated from the inside to reveal the major features of the lunar surface, and will rotate when given a slight push. This kind of levitation uses a control system with an adjustable electromagnet in a feedback loop with Hall effect sensors which allows for fine tuning of the magnetic field to exactly balance the pull of gravity. 


Infinity Mirror Light Bulb

Available as a light bulb with screw in base, or as a USB Lamp

From Amazon: BUY NOW Minimal Lamp Base 

Infinity Mirror Light Bulb: illusion of depth from multiple refections. This glass bulb is partially coated inside and out with a thin metal layer. The metal layer is made thinner in a pattern of small circles to produce iridescent colors through thin-film interference effects. When lit from within by white LEDs, multiple reflections on the curved contour create the firework like spray of light and color. So much physics going on in this inexpensive novelty bulb! 

Plasma Globe

Plasma globes are now available in many sizes and levels of quality. Here is a source for reasonably priced quality globes: 
From Educational Innovations: BUY NOW Plasma Globe 

From Amazon: BUY NOW Plasma Globes 

Plasma Globe: low pressure noble gasses exhibit glow discharge from high voltage, creating plasma filaments that rise upward due to heating- shown here in slow motion. 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

Magnetic Suspension Lamp

Available for under $100 US:

Magnetic Suspension Lamp 

From Amazon: BUY NOW 
Magnetic Suspension Lamp 

Magnetic Suspension Lamp: not only does this lamp defy gravity, the LEDs in the bulb are powered through wireless induction (no batteries needed). This kind of levitation uses a control system with an adjustable electromagnet in a feedback loop with Hall effect sensors which allows for fine tuning of the magnetic field to exactly balance the pull of gravity. If this lamp design is unplugged (or the power goes off) the bulb assembly does not fall, but instead snaps onto the upper armature via strong permanent magnets embedded within. Amazing physics demonstrated by clever engineering! 


Slow Dance

This finally crated kinetic art piece avaiable here: 

From Wonder Machines: BUY NOW: Slow Dance

From Art of Play: BUY NOW: Slow Dance

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.

Celestial Sphere: the Stars of the Night Sky

Created by Clemens & Christoph of CinkS labs: Available in a cube too! 
From CinkS Labs: BUY NOW Star Constellations in a Sphere 

Click here for Universe Sphere

Celestial Sphere: the positions of 5068 stars as they appear in the night sky- along with 88 constellations, laser etched into a crystal sphere. This globe includes all stars of sixth magnitude or brighter- basically all the stars that the average and unaided human eye can see in the sky. 

Frozen Lightning Lamp

Quality lightning figures are available here: 
From eBay: BUY NOW 
Lightning Lichtenberg Sculpture

Frozen Lightning Lamp: a Lichtenberg fractal created by electron discharge from a charged acrylic insulator. A piece of nonconducting acrylic is filled with electrons using a linear accelerator and then discharged to ground with a flash and bang- the figure is the permanent result. Electrons typically will not flow through an insulator, but a high velocity beam of them from a linear accelerator allows the electrons to tunnel deep into the plastic and build up a very large charge slowly. Such a large charge can then create a high enough voltage to create a breakdown arc which is hot enough to leave the fractal pattern. This piece is part of the Captured Lightning Sculptures series by Stoneridge Engineering LLC. 


KaleidoFlow Fluid Display Cell: The Glorb

KaleidoFlow fluid and associated devices available here:

From Laminar Sciences Corp: BUY NOW: KaleidoFlow Rheoscopic Fluid

KaleidoFlow Fluid Cell: the phenomenon of streaming birefringence colorfully reveals the temporary sheer stresses induced in a liquid by a moving plastic sphere. The “Glorb” device design features a cylindrical cell with polarizing filters as the top and bottom windows and filled with this special rheoscopic fluid and a plastic bead. This assembly then slides into a base with white LEDs to supply backlighting. Many thanks to Laminar Sciences Corp for supplying this beautiful display cell and bottles of KaleidoFlow fluid for experimentation.

Infinity Mirror Lamp

Inexpensive and a few models to choose from: 
From eBay: BUY NOW Infinity Mirror Sphere Lamp 

Also sold as a lightbulb: 
From Amazon: BUY NOW Infinity Mirror Firework Bulb 

Infinity Mirror Lamp: illusion of depth from multiple refections. This glass bulb sphere is partially coated inside and out with a thin metal layer. The metal layer is made thinner in a pattern of small circles to produce iridescent colors through thin-film interference effects. When lit from within by white LEDs, multiple reflections on the curved contour create the firework like spray of light and color. So much physics going on in this inexpensive novelty lamp!

Luminglass

These are fairly inexpensive and use two AA batteries. Great for a rave or a physics class! 
From Amazon: BUY NOW Plasma Disk 
From eBay: BUY NOW Plasma Disk 

Larger versions available here: 
From eBay: BUY NOW Luminglas Plasma Disk 

Luminglass: with audio modulation. Tesla (high frequency) coil within a noble gas discharge tube just like a plasma globe- these lightning disks also have phosphor covered dielectric pellets that create most of the light when excited by current flow. The intro to Tool's Sober provides audio with sufficient dynamic range to demonstrate the modulation effect.


Vintage VFD Tube Clock

Fully assembeld high quality clocks available here:

From Etsy: BUY NOW: VFD Tube Clock

Vintage VFD Tube Clock: before seven segment LEDs there were Vacuum Fluorescent Display tubes in which zinc oxide coatings emit green light when bombarded by electrons under high vacuum. A phosphor coated anode segment only illuminates if it and the grid (seen in close up) are both energized at positive potential. This clock features an eight digit IV-18 display tube manufactured in the 1990s and cofigured to power up via a USB cable - old tech meets modern electronics in an elegant acrylic case.

Viscous Flow Mixing Bulbs: art from mixing high viscosity fluids. Each LED bulb from EP Designlab captures a unique pattern based on the physics of laminar flow folding resulting from the mixing of viscous fluids- in this case silicone resins. When the resins cure the pattern is captured and frozen in place ready to display as illuminated by an array of 5 LEDs in the standard E26 bulb base. With this process no two bulbs are alike, and all capture intricate mixing physics.
