    This was a wonderful activity. They were fascinated by our snowman and we talked about super saturated water. Sugar solution (rock candy), salt solution, and borax crystals. However, the crystals are now encrusted on the bottom of my glass vase. How did you clean them off? More boiling water?


    • I’m so glad you liked it! And yes, if you add more boiling water, the crystals to dissolve again and you should be able to then just pour it down the drain. Good luck!
