DIY Black Light Phone Hack / Tutorial

In today’s video I’m going to show you a great idea about how to make an ultraviolet lamp at home. We won’t do it from the very beginning. We are going to turn a simple flash of a mobile phone or a simple flashlight into an ultraviolet one. This life hack is far from a real ultraviolet, but a hand made ultraviolet is also quite good. In the video you can see the result and a tutorial of how to make an ultraviolet flashlight or flash at home. Have a nice viewing.
