DIY UV Light:

Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. The UV light is used to sterilize surgical equipment and the air in operating theatres. UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntan. However, too much exposure to UV radiation is damaging to living tissue. You can make your very own UV light with the phone flash. A DIY UV light is not that difficult after all.
