Rock Candy

The kids have requested that we make rock candy. Thanks to some Googling, I found an easy recipe with a few options. We’re going to go plain flavor, with color on wood skewers. Also, I’ve tripled the recipe here for my 3 kids.

  1. Preparation:
    • Supplies:  wood skewers, granulated sugar, food coloring, large clothespins.
    • Find a spot to set 3 jars where they will remain undisturbed, but watchable for 2 weeks.
    • Prepare glass jars with labels for each child (just in case they pick the same color)
    • Have three large clothespins ready to go. Test to make sure they fit over the mouth of the jars.
  2. Bring 6 cups filtered water to a boil.
  3. Stir in the 12 cups of sugar in 1/2 cup increments.
    Stir with a spoon after each addition until the sugar is dissolved into the water. Stir until water is clear. This will take longer as more sugar is added.
  4. Remove the solution from the heat and allow it to cool for 15 minutes.
  5. Pour the solution into clean glass jars almost to the top of each jar.
  6. Add food coloring and stir with a clean skewer.
    Use a different skewer for each jar/color.
  7. Wet a skewer or popsicle stick briefly with water and roll it in granulated sugar. Allow it to dry.
  8. Place the skewer in the middle of the glass – not touching the sides and the tip does not touch the bottom of the glass.
  9. Clip with the clothespin close to the spring so the clip will sit over the mouth of the jar.
  10. Place a paper towel over the jar with a hole for the skewer.
  11. Wait 1 week for your candy to finish crystallizing without touching or tapping the experiment.

We aren’t quite ready to get this going, but I’ll post pictures when I do! :D
