Make Glowing Water Make glowing water with the help of a black light in this fun science experiment for kids. Tonic water doesn't look very strange under normal light but what happens when you look at it under a black light? Does the dye from a highlighter pen do the same thing? Find out what happens and why it happens with this cool experiment that you can do at home.
Glow Painting! 1. Carefully pop off the back of a Sharpie accents highlighter using a knife. Yellow or green works best. 2. Pull out the innards, and cut the plastic. Be careful, it's messy! 3. Put it in half a plastic cup of water. 4. Turn on the blacklight, turn off the lights, and give those kids some white paper!
