Make Fluorescent Glowing Liquid

Make amazing glowing fluorescent liquid at home using the insides of a yellow highlighter pen!

This is so easy to do!

Extracting the fluorescent liquid from a highlighter pen to make glowing fluorescent liquid is so easy, you should try it for an eye-opening science experiment.

We had a go at extracting fluorescein at home recently and we were amazed at how bright the fluorescent liquid was. The kids loved it, just pouring it into the containers was really satisfying. We wrote secret messages with it and drew pictures too, which looked awesome under UV light! Fluorescein from these pens is safe to handle too – win:win!
