- Epsom salt
- a tablespoon
- a cup of water
- a paper circle
- a jar lid
- Cut out a paper circle the same size as the jar lid. Put the circle in the lid.
- Measure 4 big tablespoons of Epsom salt. Don't worry if you add too much - the more, the better.
- Dissolve all 4 tablespoons in the water and stir the mixture thoroughly.
- Pour the water mixture into the jar lid. Stick the lid in a place where it won't be disturbed. It will take a few days, but let the water evaporate and see what happens!
What shape did your Epsom salt crystals turn out to be?
