Make Glowing Water
With this simple project, kids and parents will create "glowing water" by adding the contents of a non-toxic highlighter to water and using a flashlight to create a "glowing" effect. This project is a great way to learn about bioluminescence in nature.
Materials
Before You Play
Explain to your child that some creatures, like fireflies and glowworms are bioluminescent— they have the ability to make their own light, which makes it look like they are glowing. There are also many ocean creatures, including the lantern fish and mauve stinger, that have this ability. Scientist estimate that 90 percent of deep sea animals — those that live deep down where it’s darker — are bioluminescent. Bioluminescence can help animals see in the dark, create camouflage or attract others.
Directions
Fill the container with the water.
Pop off the back of the highlighter and pull out the ink soaked felt that is inside.
Put the highlighter felt under the water and squeeze it until the water is stained with the highlighter ink.
Turn off the lights, place a flashlight under the jar, and watch the water glow! As you admire, start a discussion with your child: What other things might glow in water? Do any fish glow under water? Why would a creature living in the water need to glow? Would this be helpful to those creatures living near the sunlight at the top of the water or those deep in the depths of the ocean? Why?
