Family Science: Geodes and Crystals

 I keep a box of geodes on hand for a fun afternoon.  HST has 10 Geodes for $13.  Here are the directions for opening geodes.  We put them in socks and hammer them open—which explains why I keep a box on hand.  We open geodes outside on the sidewalk.  Try making your Crystal Egg Geode.  Read the instructions carefully.  Be sure to coat the egg shell with glue and alum crystals to serve as seed crystals.  Another classic crystal project is the Salt Crystal Garden using Mrs. Stewart’s Bluing.  HST has Five Ways to Grow Crystals.  Alum crystals make nice, large crystals.  Bluing can produce masses of white crystals.  My favorite is Magic Rocks.  So cool.
