Using a few items from around the house you can create a crystal Christmas tree.
* Uniodized salt
* Mrs. Stewart's Bluing
STEP 2: Cut the sponge into the shape of a Christmas tree.
STEP 3: Place the Christmas tree sponge into the center of the saucer.
STEP 4: Pour the crystal solution over the Christmas tree sponge.
Mrs. Stewart's Bluing is a suspension of small particles of blue powder. As the liquid evaporates, crystals form around the blue powder. The ammonia is added to speed up the evaporation process.
