Making a Crystal Garden

There are many kinds of gardens, and some of them don't require plants.  Making a crystal garden using household items can be a fun science project for children.  Here's how:


1 aluminum pie pan
5 pieces of plain charcoal (untreated)
6 Tbsp. water
1 Tbsp. ammonia 
6 Tbsp. bluing (a laundry product)
6 Tbsp. salt
a few drops of food coloring


Mix the ammonia, water, salt, and bluing in a glass bowl or jar.  Place charcoal in the pie pan.  Pour the liquid mixture over the charcoal.  Dot with the food coloring.  Use a variety of colors if desired.  Place in a dry place and watch it grow!
