![]() Phosphorescent paint Pearl Scene using phosphorescent paint, Irving Berlin's 1921 Music Box Revue The effective wattage needed to light larger empty spaces increases, with narrow-band light such as UV wavelengths being rapidly scattered in outdoor environments. Both types of paints have extensive application where artistic lighting effects are desired, particularly in "black box" entertainments and environments such as theaters, bars, shrines, etc. Such a "black out" effect will minimize other awareness, so cultivating the peculiar luminescence of UV fluorescence. Since patterns painted with this type are invisible under ordinary visible light, they can be used to create a variety of clever effects.īoth types of fluorescent painting benefit when used within a contrasting ambiance of clean, matte-black backgrounds and borders. Invisible fluorescent paints appear transparent or pale under daytime lighting, but will glow under UV light. Visible fluorescent paint also has ordinary visible light pigments, so under white light it appears a particular color, and the color just appears enhanced brilliantly under black lights. Fluorescent paints are best viewed in a darkened room.įluorescent paints are made in both 'visible' and 'invisible' types. ![]() It has a dark blue filter material on the bulb which lets the invisible UV pass but blocks the visible light the bulb produces, allowing only a little purple light through. So viewing fluorescent paint requires a longwave UV light which does not emit much visible light. ![]() The painted surface also reflects any ordinary visible light striking it, which tends to wash out the dim fluorescent glow. Human eyes perceive this light as the unusual 'glow' of fluorescence. The fluorescent chemicals in fluorescent paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Fluorescent paint is available in a wide range of colors and is used in theatrical lighting and effects, posters, and as entertainment for children. These UV wavelengths are found in sunlight and many artificial lights, but the paint requires a special black light to view so these glowing-paint applications are called 'black-light effects'. every day and has hundreds of adoptable animals.Fluorescent paints 'glow' when exposed to short-wave ultraviolet (UV) radiation. Lee Animal Care Center, the city`s pound, conveniently located at 2741 S. And he`d have to make a trip to the David R. All told, the neighbor would pay $30 to $40 to bail out Fluffy. The neighbor can get his cat back, but it will cost him there`s a $10 to $15 redemption fee (depending on size), $2 a day for care and probably a rabies innoculation (cats almost never wear their rabies tags). The Animal Care and Control people will pick up the cat and take it to its facility. (The investigator also is empowered to issue citations for animal cruelty, if such conditions exist.) If the neighbor won`t cooperate or should deny that the problem exists, the department will lend you, free of charge, a humane (i.e., painless) animal trap that you can use to catch the offending cat. If you complain to the city`s Commission on Animal Care and Control (650-1400), it will dispatch an investigator who will report the complaint to the offending neighbor. In Chicago, any pet not in its own yard or under its owner`s control is legally a stray animal. Coffee grounds are good for the soil and give off a pleasant aroma, two big advantages over animal, uh, leavings.Īnother idea was suggested by a condo association whose grounds were being used by a nearby neighbor`s pet. Then she spread wet coffee grounds on the spots in her yard that the cats liked best. One woman spread cat box filler beneath the bushes on her neighbor`s property and deposited the cat droppings there. Note: I heard from a few readers who had additional suggestions for the man whose neighbor`s cats were using his lawn for a litter box (April 26).
