Steps:

1. Add two cups of boiling water in each of your mason jars (Please ask an adult to help handle the boiling water!).

2. Then add 40 drops of food coloring and stir.

3. Stir in ¾ cups of alum powder into the water, ¼ cup at a time. Stir well each time until it is dissolved.

4. Tie the dried glue ball to a pencil or wooden spoon. Lower the ball into the Mason jar, placing the pencil on top of the jar. Be sure the string is long enough so the ball will be submerged in the water/alum mixture. The ball should be suspended, not touching the sides of the jar.

5. Then let them sit in the jar overnight or for more than 8 hours.

6. Rinse them in the sink and dry them with a paper towel. However, I would use gloves to rinse off your crystal so you don’t dye your hand in the process.
