Water that glows in blacklight can be a visually impressive party favor, decoration, or — as YouTube commenter SNAKY put it — “this is great for water-cooling the gaming PCs and putting ultra violet lights inside!”
In this short video, Dr. Anne Helmenstine of About.com shows us how we can make permanent glowing water with the aid of non-toxic highlighter markers. Note: just because it’s non-toxic doesn’t mean you should drink it! What were you, some kind of paste-eater in grade school?
Don’t worry; she also shows us a type of water that glows in blacklight that is okay to drink.
Happy Glow Week!
