Color Changing Slime Color Science Experiment
In this fun and easy color science experiment for kids, we’re going to make a slime that changes colors.
- White school glue
- Thermochromic powder
- Food coloring
- Liquid starch
- Mix four ounces of glue with 1/3 cup of warm water.
- Add 2 tsp of thermochromic powder.
- Add about six drops of food coloring.
- Add ½ cup of liquid starch.
- Mix until slime forms.
- Touch cool or warm objects to your slime to observe it changing colors.
How it Works:
Thermochromic powder is designed to temporarily change colors when exposed to different temperatures. These types of color changing powders contain a molecular structure that changes at a specific temperature. The molecular changes alters the wavelengths of light it reflects at those specific temperatures which causes the color changing effect.
Make This A Science Project:
Try different colors of thermochromic powders. Try different slime activators like Borax and saline solution. Try exposing the thermochromic powder to long durations of cold by leaving the color changing slime in the freezer.
