Have you every wondered how to make rock candy?
It’s easy to grow your own rock candy! Rock candy is formed from sugar crystals that look like rock crystals and you can eat them. yum yum.
You can grow beautiful clear sugar crystals with sugar and water or you can add food coloring to get colored crystals. It is simple, safe, and fun. Boiling water is required to dissolve the sugar, so adult supervision is recommended for this project.
We started this project with a heart rock candy recipe in mind. Check out how it went.
How to make rock candy recipe
To make this rock candy recipe you will need
- 3 cups white sugar
- 1 cup water
- Optional food coloring
- pot /pan to boil in
- Mason jars to let stand in and swap out crystal jars
- Pipe cleaners to grow sugar crystals on
- Pencil or 4 to hold the pipe cleaners in place
- 5 to 7 days for sugar crystals to form
Add the sugar and water together in a pot on medium heat. Stir every 20 odd seconds to get everything mixed in nicely. Remove from the stove as soon as it starts to boil. Add your food coloring at this point and let mixture cool in the pot.
While the sugar mixture from our rock candy recipe is cooling, choose what shapes you want your rock candy to be. For my rock candy I wanted to make a few hearts but you can also just hang straight pieces in the sugar mixture
Once your sugar mixture has cooled down remove any residue and pour into your jars.
Wrap your pipe cleaners around the pencils and lower into the mixture making sure that the pipe cleaners do not touch the bottom or each other.
Depending on your weather you will need to swap out the jars either everyday or every second day. You do not want the rock candy forming anywhere else but on your pipe cleaners. Below is after a day, just look at all those crystals!
Day 7 the last day and crystals have slowed down to just a little on the bottom. My heart rock candy is ready.
Now you need to dry your rock candy. I did this by hanging the rock candy hearts in an empty bottle over night. Look at these gorgeous sugar crystals!
Your rock candy recipe is now ready.
The rock candy is ready for your party / gift or simply to munch on!
I made mine in hearts to give out as gifts with a bag of special tea and a flower. Since the rock candy is made of sugar it will sweeten your cup of tea, with love. 😀
