How to Make Glowing Water

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!

Our resident "Bob" (pictured here through the lens of photographer Jason DeFillippo) is in love with a woman who talks to animals. He has a fondness for belting out songs about seafaring and whiskey (arguably inappropriate in most social situations). He's arm-wrestled robots and won. He was born in a lighthouse on the storm-tossed shores of an island that has since been washed away and forgotten, so he's technically a citizen of nowhere. He's never killed in anger. He once underwent therapy for having an alien in his face, but he assures us that he's now feeling "much better." Fogarty also claims that he was once marooned along a tiny archipelago and survived for months using only his wits and a machete, but we find that a little hard to believe.

    I think I saw somewhere that tonic water also glows under black light :-)
