Stars made of glow-in-the-dark plastic are placed on walls, ceilings, or hanging from strings make a room look like the night sky. [29] Other objects like figurines, cups, posters, [30] lamp fixtures, toys [31] and bracelet beads may also glow. [32] Using blacklights makes these things glow brightly, common at raves, bedrooms, theme parks, and ...
The tube is then sealed at the desired length using a carbon dioxide laser. Borosilicate is preferred for its strength and resistance to breakage. In the tube, the tritium gives off a steady stream of electrons due to β decay. These particles excite the phosphor, causing it to emit a low, steady glow.
XL601, XL602, XL603, XL627, XL628, XL631 and XL632 – Cold-cathode, linear light source (glow modulator tube), gas diode with a blue-violet glow, modulation up to 1 MHz, 2-pin Octal base, for rotating-drum FAX receivers, etc.
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at
The whirly tube, corrugaphone, or bloogle resonator, also sold as Free-Ka in the 1960s-1970s, is an experimental musical instrument which consists of a corrugated (ribbed) plastic tube or hose (hollow flexible cylinder), open at both ends and possibly wider at one end , the thinner of which is rotated in a circle to play. It may be a few feet ...
Once a beloved treat of the 70s and 80s, Pudding Pops were a freezer aisle favorite that blended the creamy texture of pudding with the chill of a popsicle. Originally launched by Jell-O, these ...
A Geissler tube is a precursor to modern gas discharge tubes, demonstrating the principles of electrical glow discharge, akin to contemporary neon lights, and central to the discovery of the electron. [1]: 67 This device was developed in 1857 by Heinrich Geissler, a German physicist and glassblower.
