I made good on my promise of posting a picture of our crystals. I never cease to amaze!
*added after posting: I used distilled water when we made the orange star. It only took 4 hours before I realized I better hurry and pry them out of the jar. I also did this same activity at work and we left the crystals in the jar for several days because we used regular tap water and it took longer for them to grow.
Let me know if you do this activity and how long it takes before you have crystals.
