Make Your Own Rock Candy

Did you know that making your own rock candy will help kids learn about the process of crystallization? Try out this super cool science experiment that leads to a very tasty treat!

You’ll need: water, sugar, a pot, a jar, wooden sticks and food coloring

Instructions:

1. Pour two cups of water into your pot and bring it to a boil on the stove.
2. Next, add in four cups of sugar. Stir until all of the sugar is dissolved.
3. Once the solution has formed, if you want to add any flavors like vanilla or mint, add them now. Then, let the solution cool for 15-20 minutes.
4. While the solution cools, wet your wooden sticks and roll them in granulated sugar. Let them completely dry.
5. Once the sugar solution has cooled, add in your food coloring that you want for your rock candy.
6. Pour the solution into a jar and insert the sugar coated wooden sticks into the center of the jar, making sure it does not touch the bottom or sides of the jar. To make more than one rock candy stick, divide the solution between several smaller jars or use one large jar that has room to insert more than one wooden stick.
7. Secure the wooden stick in place using a clothespin and then cover the top of the glass with a paper towel. Poke a hole in the towel for the wooden stick to go through.
8. Leave the jar in a cool, quiet place and the crystallization process will occur over the next two weeks. Watch the crystals grow larger with each day and once the two weeks is complete, remove the sticks and let them dry on wax paper.
9. Once the rock candy is dry, dig in and enjoy!
