Let There Be (Black) Light
Through the years, the black light has proven itself one of the coolest inventions of man. People use it to make the most creative, eye-catching black light poster, but did you know that announcing parties in clubs, activities in parks, and other events on a big sheet of paper is not the only thing the black light can do? In fact, a black light poster may perhaps be the least in importance as far as black light uses are concerned. If you want to find out what these are, you’re in luck because this article is all about showing you the many things the black light can do.
(Black) Light It Up
Black lights offer a wide variety of practical applications, some of them may just be able to surprise you. For instance, did you know that black lights, commonly associated with artistic tendencies, are actually used by appraisers in the detection of forgeries made in antique objects? These days, many paints are designed to contain phosphors that have the power to glow under black lights; meanwhile, paints made eons ago do not contain phosphors at all. Thus, the presence of anything that glows in purportedly antique finds instantly renders such things as fake. Impressive, right? That’s just one of the many amazing purposes of the black light.
Another one involves your safety. The world we live in today is arguably one that is dominated by machines. Through technological advancement, man has found help in computers, gadgets, and appliances, relying on modern innovations for the most important aspects of his life, such as business and even romance. But machines are not perfect – they encounter problems throughout their lifetime and are sometimes already created with defects, making them hazardous to man. Thanks to the back light, repairmen can find invisible leaks in faulty machinery. All they have to do is inject a bit of fluorescent dye onto the fuel supply, and then illuminate this with black lights. For instance, repairmen may find an invisible leak in your air conditioner by putting some fluorescent dye to its refrigerant. This well help you avoid getting electrical accidents.
Aside from repairmen, forensic scientists also find use for the black light, namely to analyze crime scenes. For instance, they pick out fingerprints with the use of a fluorescent dye placed under a black light, isolating potential fingerprints from other substances, such as surrounding dirt and dust. Using black lights also help forensic scientists find semen and other bodily fluids, which may help shed light on the investigation. Now, isn’t this a far cry from the black light poster, which most people think is the only purpose of black lights? Keep searching for more information about black lights and you’ll surely find more of their fantastic uses.
