Transform tiny salt crystals into gigantic ones. Pour 1 cup WATER into a saucepan. Have a parent bring water to a boil, then remove from heat. Add 1/2 cup of EPSOM SALT and stir until it dissolves (we also added food coloring for fun). Keep adding salt until it no longer dissolves when stirred (1/4 to 1/2 cup more). Let cool, and pour into a glass jar. Tie a cotton string to a pencil, and tie a metal washer to the other end; string should be long enough so washer hangs no less than on inch from the bottom of jar. Set pencil on jar with washer dangling inside. Watch over the next few days (break away any crust that forms at top of the jar): As the water evaporates, the salt left behind will join together, forming large crystals. To keep your salt formation on display, remove the salt-covered string and hag it in a clean jar.
