This paint glows under black light.* With only two ingredients, it’s completely non-toxic (you could eat it), and it will brighten any black light party.
What you’ll need:
- 1/2 cup tonic water
- 1/2 cup cornstarch
1) Pour the tonic water into a small bowl and let it rest until it loses its fizzy.
2) Stir the two ingredients together.
3) Using paint brushes, decorate colored construction paper, skin, or other non-phosphorescent surfaces. (Most white papers won’t work because they also glow under black light. I used black construction paper.)
While working on my Spicy Alphabet book, I learned that tonic water glows under black light. I have a black light at home (who doesn’t?), so I tested it out.
It turns out tonic water ice cubes also glow under black light:
As does boiling tonic water:
Here’s the paint applied to my face:
When working on this post, I first tried adding tonic water to a variety of paints. None of them worked. The pigments in the dyes seemed to block tonic water’s glow. Finally my husband and I walked around our kitchen waving the black light over all the foods in our pantry. Cornstarch had the best luminescence, hence this recipe. We tried a few different ratios. The one-to-one ratio had a good consistency.
Most of my projects involve a lot of trial and error. Here’s a video I shared on my Facebook Page a while ago (from my Summer Science series):
What can I say? I like to play!
