After nearly 20 years of crime scene investigation TV, most of us know what happens when you shine a black light on the walls of a hotel room. Disgusting. Here’s an even scarier thought – what’s lurking in your home or office? Wouldn’t you like to know what needs to be cleaned or what surfaces to avoid touching? From pet urine stains to the light switches at the office, there have got to be dozens of things to see. The best way to solve a problem is to shine a light on it!
Hefty.co has posted a video that shows you how to make a black light using your phone’s flash, Scotch tape, and two Sharpies. With this beacon of discovery, you can easily find the repulsive messes you want to avoid or clean up. That, or have an impromptu disco dance party. Your choice. See how at the link below!
