Grow crystals in the sun with Epson salt. In aluminum cake or pie pan cut a piece of black paper the size of the bottom. In a bowl pour 1/4 cup of warm water and add one tablespoon Epson salt. Stir until the salt dissolves.
Pour the salt mixture on the black paper and let it sit in the sun until the water evaporates.
The crystals we grew. We have some of those jewelers loops that we look at everything with. I put the loop over the lens of the camera to get these pictures the crystals are really quite small.
The salt dissolves in the water and when the water evaporates the salt forms crystals. Using table salt does not give the same results because table salt and Epsom salt have a different chemical make up.
