Have you ever wanted your own black light? Well, this handy video, from 'GadgetHacks', will show you how. Perhaps you want to go all CSI and look for genetic evidence that can only be seen under black light? Or, maybe you want to go on the lookout for germs and other bacteria in your home, so you can scrub them into oblivion! But there's also the possibility, you just want to create a '70s style psychedelic look in your room. Whatever the reason, we won't judge! Rather than going out and buying a special black light, you can make your own with a smartphone, some tape, a blue sharpie, a purple sharpie and a highlighter. So, check out the video and you, too, could have your very own black light!
