Overview

A proper mad science laboratory requires mysterious potion-filled test tubes lit with eerie colors to flicker in thier rack. Build this display for maximum creepy effect!

Flourescent pigments mixed with water make for a creepy-cool luminescent potion when lit with ultraviolet light, especially as they flicker and blink based on a microcontroller pattern you design.

You can use this technique to make test tubes glow in a standard test tube rack, or build your own from black iron pipe fittings and laser-cut acrylic for some next level spookiness!

Don't have any UV pigment? No problem -- get some tonic water instead! The quinine in tonic water fluoresces a cool blue color under UV light.
