@xahlee we used to make rock candy as kids; it's still a thing. You'll find it in places themed "old fashioned" -- it was available at several historical sites in our state parks, and occasionally, might be found in a gas station or country store. It's certainly for sale on Amazon at ridiculously high prices: https://www.amazon.com/Cotton-Individually-Wrapped-Crystal-Sticks/dp/B00OGQH9FS
