Day 1 – How to Grow Crystals with Kids

Put coal (or cut up sponges) on a pie plate. Spray the coal until it is moist, but there is not any extra water on the bottom.
How to Grow Crystals Mix together: 3 tablespoons uniodized salt, 3 tablespoons ammonia (smells really strong!), and 6 tablespoons bluing. Stir until the salt is dissolved.
getting ready to grow crystals
Pour the mixture evenly over the coal. Add a little water, stir, and pour the remaining mixture onto the coals. {You can see 2 year old Tinker Bell was fascinated with what was going on too!}
our fun homeschool science Put drops of food coloring over the coals. {Areas without food coloring will be white.} Sprinkle with 2 TAB more of salt.
