After making our Penguins of Madagascar cake, which used a lot of rock candy, I received many requests for a video on how to make your own homemade rock candy. So, I started practicing . . . two weeks ago! This activity takes quite a long time to grow (1-2 weeks), so be prepared a head of time if you need homemade rock candy for a project.
Making this recipe brought me back to high school chemistry and supersaturated solutions. I did not really want to go back to high school in my mind, but I had to. All for the sake of rock candy. As far as the actually creation of this recipe, it is fairly simple, and straight forward. “Supersaturation is a state of a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances”, thank you Wikipedia. Basically, you need to get as much sugar into the water as possible, in order to make sure that the rock candies will grow.
- ensure that the stick does not touch the bottom or the sides of the glass
- make sure that the sugar has dissolved in the solution completely
- add colour and flavour to make it delicious looking and tasting!
