I boiled sugar water for rock candy, last night. Each of the kids picked their color, and we put some in their cup, then poured in the boiling sugar water. I broke long bamboo skewers in half, and put them in the cups of colored sugar water. They were so excited. I told them it will take time for the crystals to grow. Every hour, they're running to the kitchen to see if the crystals have gown any. Patience, grasshopper.
