If you've ever wanted to find out just how gross your unbearably slobbish roommate's room is, there's an easy way: a blacklight. But if you don't feel like going to the store to buy one, there's an even easier way, and it involves your smartphone.
With this simple little trick shown by YouTuberÂ Endo75, now you can illuminate (literally) all the unspeakable grossness you've suspected of certainÂ places for so long. Just don't let your girlfriend use it on yourÂ room.
All you'll need are blue and purple sharpies and some scotch tape.
Start by laying a layer of tape over your camera's flash light.
Then color over it generously with the blue sharpie.
Do this same thing another time, still using the blue sharpie...
And finally, a third, this time using the purple sharpie.
Then, it's as easy as turning the lights off and snapping a picture with the flash on. Just make sure you prepare yourself for what you'll see.
