Stain Detector Helps Detect Grody, Invisible Stains

While it’s being marketed as a tool to help you find hidden stains so you can make your pad smell better, we know it’s really so you can all play CSI at home.

The Stain Detector Light uses the same UV technology that the detectives use to find “protein stains”, blood, bile, or, uh, what-have-you. Wanna scare someone? Visit them in their hotel room with this thing pointed at their mattress. Yah, ew.

The best part is that it’s only $7, and you can play detective. Or check invisibles stamps at Disneyland.
