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.
These lamps can often be found on eBay:

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.
Amazing application of high resolution far field holograms. The only available source I know of for projection holograms at this high resolution is this supplier of industrial samples

Need a laser pointer? Incredibly, you can get 3 (one of each color) for under $20 (including S&H):
From Amazon: BUY NOW Red+Green+Purple Laser Pointer
Diffractive Optical Element: images produced by constructive and deconstructive interference of coherent laser light. The patches of microstructure on the surface of this transparent plastic are far field holograms- transmission holograms, but with the image at infinity. Side by side images from two different laser wavelengths (red 635 nm, green 520 nm) shows clearly the red image is larger than the green since diffraction angle is proportional the wavelength. So much physics here!
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!
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.

Blue Lightning Lamp
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.

The diffraction effect glasses used here is this kind:
From Amazon: BUY NOW Diffraction Glasses
Neon Flicker Flame Skull Bulb: no flame but instead emission spectra from excited neon gas due to the presence of a discharge electric current. The breakdown voltage of a gas (the minimum voltage needed for a current to flow) depends on the pressure of the gas in the bulb. The flickering effect comes about because the current flow will increase the temperature near it, which raises the pressure and affects the breakdown voltage near the current- so the glow from one area can only last as long as it takes to heat up and raise the breakdown voltage which kills the current in that area. In other physics, a diffraction grating shows that neon only emits light in specific wavelengths- mostly reds and yellows at AC house voltages. ?

From eBay: BUY NOW: Lighting Plasma Lamps
Lava Lightning Lamp: low pressure noble gasses glow due to discharge from high voltage and stimulate colored phosphors to emit yellow, blue, and red in this vintage device by Lava. A small high frequency coil at center creates the high voltage potential between the center electrode and the outer glass casing 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 240 fps slow motion. Another of my vintage plasma lamps in my collection.

The floursecne can only be achived using short wave UV lamps whace can be expensive. Less expensive used and vintage devices are often found here:
From eBay: BUY NOW: Short Wave UV Lamps
Bright Mineral Fluorescence: under short wave ultraviolet light Willemite fluoresces bright green and Calcite (with trace percent Manganese activator) glows orange-pink in this spectacular specimen from the Sterling Hill zinc mine out of New Jersey. The brilliant colors of fluorescence seen here come from exposing the rock to short wave UV (less than 280nm) using a vintage Mineralight brand light.
This plasma mug was sold in the 1990s but can be found on eBay often:

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!

UV (405 nm) Laser pointer
Fluorescent Ooze Tube with UV 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 the UV laser light to visible 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?
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.

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.

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.

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!
