Create Glowing Liquid!

Here's a simple method to make a liquid that glows under UV light, creating a great effect for a toxic, radioactive prop that you could use in a zombie or nuclear-themed escape room, haunted house, or halloween decoration.

Only equipment required is tap water, a highlighter pen, and a source of UV light.

You can also write with that very same liquid on a paper and make some invisible ink revealed by UV light :)

It's a quiet and quick simple trick

Why does it look like you are holding a light under the liquid

[reloadnorth]

Hello. Can this then be used to dilute water based paint for an airbrush, and have a glowing effect with a blacklight?

Dude: I'm going to hold a UV light underneath it so I can demonstrate how it would react.
People: that's faek, omg, yur holding a light.

If you look carefully at his hand then you'll see a light coming out between 2 of his fingers, which means he is holding a light under it. (Maybe)

[naseemshaafi]

Please tell quickly how long will we have the light

[LSG]

It wont work his just holding an LED in his hand that lights up the bottle with the yellow water u can clearly see the lights between his fingers

Nice, but not good enough as it is clear that you're holding a lamp underneaths the bottle xD nice try though

[antmantheoriginalyt]

Reason: The way he is covering the bottom of the cup where he is covering he put a light.
