GEODES

My sister showed up for a science experiment last week on making your own Geodes.
1. Save some egg shells and rinse them out.
2. In a glass bowl have kids pour epsom salt into 2 cups warm water. (I didn't use enough salt so be generous).
3. Add food coloring if you would like (2 drops)
4. Pour into egg shells and wait.
After the water has dissolved, after about three days the crystals will start to form.
HAVE FUN!!!
