We are nerds at heart and had to try this fun science experiment with the kids. It took a lot of patience waiting for this to happen, but I think they were pretty excited to see the crystals forming on our rock candy. They got to watch it over a period of about a week and we finally ended up with these. Pure sugary goodness.
DIY Rock Candy RecipeIngredients:
4 cups sugar
1 cup water
Food coloring of your choice
Clean glass mason jars
String, cut into 8-inch lengths
In a medium saucepan, heat 2 cups of the sugar and the water. Do not bring to a boil. Stir until the sugar is completely dissolved. Gradually add a few drops of the food coloring of your choice and the additional sugar, stirring continuously until all the sugar is dissolved.
Pour the solution into a clean glass jar and tie the pieces of string to the pencil and suspend them across the mouth of the jar so that the ends hang into the sugar water.
Crystals suitable to eat will form in an hour and continue for several days to a week. Pieces can be broken off and eaten after the first hour. (But, try to hold out for big crystals!)
Although you may see quick results in small measure, the larger rock candy crystals you're accustomed to seeing in the candy store will take at least a week to form.
