An old-fashioned project that always provides wonder and excitement is a crystal garden. Gather several small stones, or use barbeque briquettes. Either will work just fine.
USE CAUTION WHEN HAVING AMMONIA AROUND YOUR CUBS!!!
- 6-7 Charcoal briquettes, or stones
- Shallow bowl
- 6 tablespoons salt
- 6 tablespoons laundry bluing
- 6 tablespoons water
- 1 tablespoon ammonia
- Food coloring
Procedure: Place the briquettes or stones in the bowl. Mix all the other ingredients together, except the food coloring. Pour the mixture over the stones with a spoon. You may have extra; just store it in a covered container and add to the garden over the next few days to keep it growing.
Drop food coloring over the coated stones.
Crystals will begin to form in about twenty minutes. Pour more soluttion and add more coloring every day, and the garden will contiue to change and grow.
