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.
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!

Magnetic Suspension Lamp
From eBay: 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!
Available as a light bulb with screw in base, or as a USB Lamp

EP Lights LED Bulb Art
coupon code: PHYS2019 (10% off)
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.
The amazing art of Anne-Lise King available here:
From Etsy: BUY NOW: Kino Lamp Polarizing Art Lights
Lampe Kino: Art from from the manipulation of polarized light. These videos showcase two designs by artist Anne-Lise King, and each design can itself be displayed in numerous ways depending on the orientation of the polarizing filter and the layering of plastic imaging sheets. Light has an orientation, denoted as polarization, and a polarizing filter can be used to block certain orientations. The colors produced here come from how the molecular structure of plastics can rotate the polarization of light that passes through- light corresponding to yellows and greens gets rotated in plastic in proportion to their frequency, red and blue frequencies only a small amount. The images here are constructed with different layers of plastic to rotate the light by differing amounts. Polarizing filters are then added to allow only certain frequencies (colors) of light through.
These are fairly inexpensive and use two AA batteries. Great for a rave or a physics class!

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.

DIODER Variable Color Lamp
Explore the physics of light and color with this excellent kit:
From Amazon: BUY NOW
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 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
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.

Vintage fiber optic lamps like this one are available on eBay most of the time:
From eBay: BUY NOW Vintage Fiber Optic Flower
Fiber Optic Cactus Lamp: this vintage 1980s fiber optic lamp was found at a local thrift store- and it still works! 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.

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.
These gometirc candle holders are available from the artist's store here:
From glasperlenstern.de: BUY NOW: Glass Bead Star Tea Light
Dresden Glass Bead Star: concentric designs of spherical glass beads produce geometric symmetries of shadow and refracted light from a tea light candle which serves as a point source of illumination. This “Glasperlen Stern” candle holder is one of many configurations offered from Dresden artist Andreas Schildhauer, each with glass set into porcelain from Freiberg.
This plasma mug was sold in the 1990s but can be found on eBay often:
From eBay: BUY NOW: Plasma Mug
An improved and beautiful version sold here:
From Etsy: BUY NOW: Plasma Mug
Tesla’s Plasma Mug: this double walled glass mug glows orange from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer that generates high voltage electric fields (but at very low current) from 8 AA batteries- which excites the neon to glow, and also serves as a coaster. This crazy item was produced by Can You Imagine Toys in the 1990s- perhaps Tesla himself would have served a good beer in this mug!
