Blacklight Paint
Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light. Black light paint should not be confused with phosphorescent (glow-in-the-dark) or daylight fluorescent paint. History The invention of black light paint is attributed to brothers Joseph and Robert Switzer in the 1930s. After a fall, Robert suffered a severe head injury that resulted in a severed optic nerve. His doctor confined him to a dark room while he waited for his sight to recover. Joseph, who was a chemistry major at the University of California, Berkeley, worked with Robert to investigate fluorescent compounds. They brought a black light into the storeroom of their father's drugstore looking for naturally fluorescing organic compounds and mixed those compounds with shellac to develop the first black light f ...

Day-Glo Color Corp
The Day-Glo Color Corp. (also styled as DayGlo) is a privately held American paint and pigments manufacturer based in Cleveland, Ohio. It was founded in 1946 by brothers Joseph and Robert Switzer and is currently owned by RPM International. It specializes in fluorescent paint and pigments, such as those used in safety applications, artwork and signage. It invented black-light fluorescent and daylight fluorescent paints and nondestructive testing methods using fluorescent dyes. History Robert and Joseph Switzer of Berkeley, California began investigating fluorescence in the 1930s using a black light to identify naturally occurring fluorescent compounds.Ensminger, David. "Black Light Panthers: The Politics of Fluorescence," ''Art in Print'' Vol. 5 No. 2 (July–August 2015). By mixing these compounds with shellac, they invented the first black light fluorescent paints. Joseph used these paints in his amateur magic show and sold magic kits based on the black light fluoresce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paints
Paint is any pigmented liquid, liquefiable, or solid mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture. Paint can be made in many colors—and in many different types. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. Most paints are either oil-based or water-based and each has distinct characteristics. For one, it is illegal in most municipalities to discard oil-based paint down household drains or sewers. Clean-up solvents are also different for water-based paint than they are for oil-based paint. Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted (such as a house.) Usually, the object being painted must be over , although some manufacturers of external paints/primers claim they can be applied when temperatures are as low as . History Paint was ...

Phosphor
A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow when struck by an electron beam (cathode rays) in a cathode-ray tube. When a phosphor is exposed to radiation, the orbital electrons in its molecules are excited to a higher energy level; when they return to their former level they emit the energy as light of a certain color. Phosphors can be classified into two categories: fluorescent substances which emit the energy immediately and stop glowing when the exciting radiation is turned off, and phosphorescent substances which emit the energy after a delay, so they keep glowing after the radiation is turned off, decaying in brightness over a period of milliseconds to days. Fluorescent materials are used in applications in which the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescent
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacuu ...

Fantasy World
A fantasy world is a world created for/from fictional media, such as literature, film or games. Typical fantasy worlds involve magic or magical abilities, nonexistent technology and, sometimes, either a historical or futuristic theme. Some worlds may be a parallel world connected to Earth via magical portals or items (like Narnia); an imaginary universe hidden within ours (like Wizarding World); a fictional Earth set in the remote past or future (like Middle-earth); an alternative version of our History (like Lyra's world); or an entirely independent world set in another part of the universe (like the '' Star Wars'' Galaxy). Many fantasy worlds draw heavily on real world history, geography, sociology, mythology, and folklore. Plot function The setting of a fantasy work is often of great importance to the plot and characters of the story. The setting itself can be imperiled by the evil of the story, suffer a calamity, and be restored by the transformation the story brings ab ...

Dark Ride
A dark ride or ghost train is an indoor amusement ride on which passengers aboard guided vehicles travel through specially lit scenes that typically contain Animatronics, animation, sound, music and Special effect#Live special effects, special effects. Appearing as early as the 19th century, such exhibits include tunnels of love, scary themes and interactive stories. Terminology In its most traditional form, the term ''dark ride'' refers to ride-through attractions with scenes that use black lights, whereby visible light is prevented from entering the space, and only show elements that fluoresce under ultraviolet light, ultraviolet radiation are seen by the riders. The size of each room containing a scene or scenes is thus concealed, and the set designer can use forced perspective, Pepper's ghost and other visual tricks to create the illusion of distance. Typically, these experiences also use a series of opaque doors between scenes to further control riders' views within a spa ...

Amusement Park
An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects. Amusement parks evolved from European fairs, pleasure gardens, and large picnic areas, which were created for people's recreation. World's fairs and other types of international expositions also influenced the emergence of the amusement park industry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Vision
Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range. Humans have poor night vision compared to many animals such as cats, foxes and rabbits, in part because the human eye lacks a tapetum lucidum, tissue behind the retina that reflects light back through the retina thus increasing the light available to the photoreceptors. Types of ranges Spectral range Night-useful spectral range techniques can sense radiation that is invisible to a human observer. Human vision is confined to a small portion of the electromagnetic spectrum called visible light. Enhanced spectral range allows the viewer to take advantage of non-visible sources of electromagnetic radiation (such as near-infrared or ultraviolet radiation). Some animals such as the mantis shrimp and trout can see using much more of the infrared and/or ultraviolet sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blacklight Poster
A blacklight poster or black light poster is a poster printed with inks which Fluorescence, fluoresce under a black light. The inks used contain phosphors which cause them to glow when exposed to ultraviolet light emitted from black lights. Overview Although black lights date to 1903 with the development of the optical filter glass Wood's glass, fluorescent ink was not developed until 1932 when the Switzer brothers were inspired by a ''Popular Science'' magazine article to experiment in their father's pharmacy. Their Day-Glo Color Corp. marketed the ink chiefly to the military before a Counterculture of the 1960s, counterculture emerged to embrace the aesthetic.Ensminger, David.
