What can I use a blacklight for?

Well golly Beaver...there are so many uses that we might run out of space.  Hmm...there's counterfeit money detection (who wants a funny $100 bill?), scorpion finding (sure beats the old way of getting stung first!), antique uranium and vaseline glass detection (don't get swindled by that dealer), AC coolant leak dye detection, (don't get caught out in the hot), bathroom & bed inspection (I hope a comment isn't needed here...), mineral hunting (keep those minerals from running away), driver's license UV markings (make sure your fake is real before you use it), UV curing (huh?), and many others.  We'll get into more detail later...
