Kids love magic: watching things appear out of thin air. When your child makes crystals form on ordinary rocks and pebbles, she'll feel just like a magician!
What to do:
Step One: Your child should go outside and gather as many rocks and pebbles as she likes.
Step Two: Rinse the rocks clean in the sink or tub.
Step Three: On the stove, boil 1/2 cup of water.
Step Four: Add 2 oz alum to the hot water and stir until the alum is dissolved.
Step Five: Pour the solution into a clear glass bowl.
Step Six: Fill the bowl halfway with the clean rocks and pebbles.
Now watch in amazement as crystals form like magic!
