Neon Plasma Glassware

Sold individually, or as a set, here:

From Etsy: BUY NOW: Plasma Glassware and Excitation Base

Neon Plasma Glassware: serve up a platter of plasma! These double walled glass mugs glow orange and blue from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer (Tesla coil) that generates high voltage electric fields (but at very low current) which excites the neon to glow, and also serves as a display platter. The inner volume of each glass varies in thickness which leads to variations in heat and pressure which in turn produces different excitations (orange and blue) of the neon gas in patterns that dance and dazzle the eye. An upcoming video will show these filled with beverages. Stunningly beautiful kinetic art and tech by creator Zerg Dragonymous.

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. 

The Levimoon

Get a levitating moon globe lamp here! 
From Amazon: 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. 


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. 

Tricolor Plasma Globe with Glow Wand

Get a globe and glow wand here:

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. 

Infinity Mirror Light Bulb

Available as a light bulb with screw in base, or as a USB Lamp 
From eBay: BUY NOW Infinity Mirror Bulb
From Amazon: BUY NOW Infinity Mirror Lamps 

Get the minimal tabletop base here: 
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! 


Pearlescent Metallic Lava Lamp

Get this metallic lava version here:

From Amazon: BUY NOW: Metallic Lava Lamp

From explOratorium store: BUY NOW: Metallic Lava Lamp

See aslo: Magnetic Ferrofluid Lava Lamp

The Lava Lamp: with new pearlescent metallic “lava”- kinetic art with an amazing amount of physics on display: convective heat flow, Archimedes principle, surface tension (note how the smaller blobs form into spheres), and immiscible liquids to name just some of the science behind this famous device. In this loop one can see shock waves ripple through the blobs as they detach, and as they recombine at the bottom. Manufactured by Mathmos and invented in 1963 by Edward Walker of Dorset, England. 

Rolling Ball Fountain

Find this and similar fountains here:

From Amazon: BUY NOW: Rolling Ball Fountain

Rolling Ball Fountain: this miniature kugel fountain features a glass sphere that sits on a socket of precisely similar shape, and is suspended on a very thin (less than half a mm) film of moving water which greatly reduces friction. The velocity of the water in the thin layer slows as it spreads out via a hole in the socket, and this hole is offset from the center so that the interaction with the water stream sets the ball spinning. A small pump provides the flow rate, and colorful LEDs illuminate the glass sphere to show off the rotation. Perhaps you’ve seen public art installations featuring giant granite spheres weighing tons and yet similarly suspended on a thin layer of flowing water. Physics principles involved here include viscosity and Reynold’s number, the Navier-Stokes equation, Bernoulli’s principle and the study of thin layer lubricants.

Lampe Kino: Polarizing Art

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.


Luminglass

These are fairly inexpensive and use two AA batteries. Great for a rave or a physics class!

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.

Neon Plasma Glass

Each glass is unique and comes with tesla coil base:

From Etsy: BUY NOW: Neon Glow Glass by TeslaCoilPro

Neon Plasma Glass: these double walled glass mugs glow orange and blue from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer (Tesla coil) that generates high voltage electric fields (but at very low current) from USB rechargeable batteries- which excites the neon to glow, and also serves as a coaster. The inner volume varies in thickness which leads to variations in heat and pressure which in turn produces different excitations (orange and blue) of the neon gas in patterns that dance and dazzle the eye. Stunningly beautiful kinetic art and tech by creator Zerg Dragonymous.

Fiber Optic Cactus Lamp

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.
