- Thin shirt cardboard
- Scissors
- Deep saucer or small bowl
- Small jar with a tight-fitting lid
- 1 tablespoon table salt
- 1 tablespoon bluing
- 1/2 tablespoon household ammonia
Instructions
-
To create the base, cut two cardboard tree shapes (about 4 inches tall and 3 inches across at the widest point). Cut a 2-inch slot in the top of one shape and in the base of the other. Join the shapes at the slots and stand the tree in a deep saucer or a small bowl.
-
In the jar, combine 1 tablespoon water, the salt, bluing, and ammonia (handling ammonia is a parent's job). Fasten the lid and shake well, then pour the solution into the saucer or bowl.
-
Leave the tree undisturbed. Crystals may take as little as an hour or as long as a day to begin to form, depending on the humidity in your home (they'll grow better in drier air). The tree will keep growing over the next few days, until all of the liquid evaporates.
