Here are the materials for the lab
Here are the finished crystals on their pipe cleaner bases.
Here are the crystals the next morning. You pour out the Borax solution (3 tablespoons Borax in 8oz of Hot water) the morning after and let them dry a day.
It's fun and meets the state chemistry standards for crystals
I hope this helps,
Love to Teach and Teach with Passion
Remember...It's not Magic, It's Science
