You only require a light source, some colorful highlighter pens, and clear tape. To make your own blacklight using regular household materials. Don’t panic and run to the shops, the chances are you’ll have all materials you need lying around the house. Ok, that’s the technical bit over, now I’ll tell you how to make blacklight (how to make ultraviolet light).
The phosphor layer is what absorbs our visible light (UVB) leaving only the ultraviolet light shining through. The fluorescent (purple) tube lights, similar to those you see at concerts and nightclubs, contain an inert gas and mercury along with an outside layer of phosphors. Why not check out how a blacklight bulb or fluorescent light works to find out in greater detail about these types of lights.
