Rock Candy, Super-saturation and Halloween, oh my!
In honor of Halloween and my solutions unit coincidentally happening concurrently, I've decided to give my students rock candy instead of the usual fun-sized goodies. Besides, who has time to read ingredient labels for peanuts/gluten/Kosher and any other dietary restrictions?? In the past, I've attempted to make rock candy in class, but it never seems to work properly. It ends up forming a giant crystal layer on the top, and the container ends up being spilled by a trouble making student. So, I'll make epsom salt crystals as a demonstration, and simply give them food-grade rock candy to calm their nerves and prevent the chorus of can we pleaseeee make rock candy?! Rock Candy in bulk is surprisingly cheap, too!
