Kid Science: Colorful Crystals

A fun project to do with your kids to teach solubility, evaporation, solids vs. liquids as well as the science behind how crystals form!

The steps:

1. Start by mixing 1/2 cup epsom salt with 1/2 cup hot water until completely dissolved (about a minute or so).

2. Add 10-15 drops of food coloring and mix well

3. Pour the cooled liquid into clear recycled take out lids (the small ones work great).

4. Allow to dry in a sunny place for about 24 hours. See how crystals form as the water evaporates!

5. Optional – punch a small hole on the edge of the lid, add a string and hang in a sunny window!
