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!

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.

Ferrofluid Interactive Lava Lamp

Two models to choose from: available here 
From Amazon: BUY NOW Ferrofluid Lava Lamp

Ferrofluid Interactive Lava Lamp: special ferrofluid infused wax allows manipulation of the blobs of “lava” with a weak magnet, adding an interactive element to the already mesmerizing physics of convective heat flow, Archimedes principle, and immiscible liquids. Love the atomic rocket theme on this updated version of the 1960s classic physics toy. 


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! 

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.


Fresnel Minor Lamp

Art Gallery: inquire about availability 
Sean Agustine March

Fresnel Minor Lamp: Microlayers of metals and metal oxides allow a slab of glass to transmit a different color than it reflects through thin-film optical phenomena such as interference and selective absorption. In this remarkable art piece, dichroic glass is combined with infinity mirror type multiple reflections creating this dazzling display of physics! Special thanks to @seanaugustinemarch for this amazing addition to my collection.

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. 

Variable Hue Lamp

This fairly inexpensive hue lamp is made by IKEA and is available here:

DIODER Variable Color Lamp 


Explore the physics of light and color with this excellent kit:

Thames & Kosmos Optical Science Kit

Variable Hue Lamp: Seeing color is both about the source of illumination and the reflective and absorptive properties of the observed object. These colorful images look drastically different as this illumination source cylces through a wide range of hues via variable mixtures of red, green, and blue wavelengths. A demonstration that explores some of the complexities underlying the physics and psychophysics of color vision. 


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

Viscous Flow Resin Lamps

on all  EP Lights LED Bulb Art 

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.

 

Lava Lamp in Time-lapse

Available here in many colors and sizes: 
From Amazon: BUY NOW 
Lava Lamps

Lava Lamp in Time-lapse: 15 minutes compressed into 15 seconds gives a different perspective on the processes involved in this classic physics toy from the 1960's. Mesmerizing physics of convective heat flow, Archimedes principle, and immiscible liquids. Manufactured by Mathmos and invented in 1963 by Edward Walker of Dorset England, the Lava Lamp is still popular today and is available in a wide range of colors. 


Fiber Optic Galaxy Lamp

These lamps can often be found on eBay: 
From eBay: BUY NOW Fiber Optic Lamps

Fiber Optic Galaxy Lamp: a vintage 1970s fiber optic lamp with a chrome “UFO” base. Note the beautiful spherical symmetry of the fiber spray- they don’t make them like this anymore! The fiber bundle is illuminated by a lamp in the base and the color shifting patterns are generated by a rotating color wheel placed between the light source and the fiber optic bundle. Fun physics at a thrift store price.

RGB Color Addition

These Light Blox are available in this nice kit from Laser Classroom, a science education supplier: 
From Laser Classroom: Light, Color and Shadow Kit 

Wikipedia has a fantastic introduction on the topic of RGB Color Theory 

RGB Color Addition: three LED light boxes demonstrate the additive nature of colored light. Mixing Red, Green, and Blue to create Yellow, Magenta, and Cyan. An object casts shadows showing the following mixings: R+G=Y, G+B=C, and R+B=M. Adding all three R+G+B produces White (a little pinkish here as the Red is a little bit bright for complete white balance). RGB color addition is the basis for all computer and TV displays- all the colors you are looking at right now on your screen are made from adding pixels of R G and B in different proportions and intensities!

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.
