I always hear about people using black lights and they all seem to use them for the same purposes (ex: checking ID’s or looking for bodily fluids on seat belts or in cars, etc.) What are some creative ways I could use a black light?

Black lights can be used to detect fake money. Some retailers also use them to spot shoplifters. Fake urine will glow under UV, making it useful for spotting invalid samples during drug testing. If you shine an ultraviolet light inside your mouth, you can see which of your teeth is rotting. There was even a TV show where forensic investigators searched crime scenes with portable black lights to find traces of blood and other substances invisible in normal lighting conditions.
