Lightning 2000 Plasma Lamp: low pressure noble gasses glow due to discharge from high voltage. A small high frequency coil at center creates the high voltage potential between the center electrode dome and the outer glass dome which is coated with a thin transparent film of metal. Current flow through the thin gas produces the glowing zigzagged path like that of lightning but more rounded. Shown here in 480 fps slow motion.

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! 

Fresnel Minor Lamp

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.

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. 

Fiber Optic Cactus Lamp

Vintage fiber optic lamps like this one are available on eBay most of the time:

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. 

Viscous Flow Mixing Bulbs

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.


Magnetic Suspension Lamp

From Amazon: BUY NOW: Magnetic Suspension Lamp 

Note: this site contains affiliate links for which I may be compensated

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!

Fluorescent Ooze Tube with Laser: stunning visual effects from a 405 nm laser pointer interacting with the viscous polyisobutene fluid in this ooze tube timer toy. The fluorescent dye converts this particular laser light frequncy to green light as the fluid stretches into thin ropes that act as light pipes while bubbles reflect and fan the beam. Perhaps the next generation Lava Lamp?

Natural Mineral Fluorescence: Four mineral specimens that emit a surprising bright glow under long wave ultraviolet light (from left to right): a clear calcite crystal glows pink, a carved obelisk of grey syenite with grains of sodalite(bright orange), a carved piece of green fuchsite with red ruby inclusions(red glow) and veins of white calcite(bright white), and a polished slab of lapis lazuli with speckles of the mineral hauynite (yellow glow). The colorful glow comes from complex quantum mechanical behavior where high energy UV photons are absorbed and then lower energy photons are emitted- the physics of fluorescence.

Coronal Brush Discharge + Flower: electric fields are concentrated at the sharp points of the petals of this ice plant bloom allowing coronal brush discharges to form miniature lightning bolts. The high voltage is supplied by a novel disk coil variation of the famous air core double-tuned resonate transformer invented by Nikola Tesla in 1891. In this novel design the coil is created using modern printed circuit board (PCB) technology producing a spiral of many conductive windings, so thin and close together it looks a bit like a gold phonograph record. Powered by a 24V DC supply, this unit is fairly safe due to a low current (mA)- the discharge feels like a light tickle (but don’t touch the electrode- it gets hot).
