Description

Create sparkling Homemade Rock Candy with just sugar, water, and a little patience! A fun, science-meets-sweets project perfect for kids, gifts, or colorful treats.


Ingredients

Scale
  • 12+ cups granulated sugar
  • 4 cups warm water
  • Food coloring (optional)
  • Candy flavoring (optional)
  • 12 wooden skewers (6-inch)
  • 6 quart-sized mason jars
  • 12 clothespins

Instructions

  1. Soak wooden skewers in water for 30 minutes, then roll in granulated sugar. Let them dry completely—this helps crystals form.
  2. In a large pot, stir 8 cups of sugar into the warm water until no more dissolves.
  3. Bring the mixture to a gentle boil, adding the remaining sugar slowly until it becomes fully saturated (about 4+ more cups). Stir constantly.
  4. Remove from heat and let the syrup cool for 20–30 minutes.
  5. Pour syrup evenly into the mason jars. Add food coloring or flavoring if desired and stir gently.
  6. Place two sugar-coated skewers in each jar, ensuring they do not touch each other or the sides. Use clothespins laid across the top of the jar to hold skewers in place.
  7. Set jars in a cool, undisturbed area for 5–10 days. Watch as crystals slowly form on the skewers.
  8. Once crystals are to your liking, remove the skewers and let them dry for a few minutes before enjoying.

Notes

  • Ensure syrup is fully saturated for successful crystal growth.
  • Do not disturb the jars during the crystallization period.
  • Add different food coloring or flavors to customize your rock candy.
  • Clean jars thoroughly before use to avoid impurities that affect crystallization.
  • Ideal for edible science experiments or party favors.
