Ingredients
- 1 cup granulated sugar
- 1 cup water
- Wooden sticks, clean string, or pipe cleaners for catching crystals
- Clothespins or clips (optional) to suspend the stick or string
- Food coloring or edible flavor extracts (optional; use sparingly)
- A spoon for stirring (preferably wooden)
- A small funnel (optional) for transferring liquid neatly
- A thermometer (optional) for checking the water temperature
- A clean jar for each batch
- Parchment for drying the finished crystals
Instructions
- Prepare the workspace and jars. Set the jar on a level surface. Place a soft cloth beneath it to help prevent slipping. Use a stable surface where the jar can remain undisturbed while the crystals grow.
- Warm the water gently. Heat the water until it feels warm, not scalding. If children are helping, an adult should handle the heated water and pour it into the jar or mixing vessel.
- Add the sugar gradually. Stir in the sugar slowly with calm, circular motions. Adding it bit by bit makes it easier to see whether the sugar is dissolving.
- Stir until clear. Continue stirring until the sugar has dissolved and the liquid looks clear. Avoid rushing this step; undissolved sugar can settle and make the solution look cloudy.
- Add color or flavor if desired. Stir in a drop or two of food coloring or a small amount of edible flavor extract. Mix just enough to blend. Vigorous stirring can create bubbles, so use a gentle motion.
- Prepare the crystal-catching surface. Wrap a thin string around a stick, or twist a pipe cleaner into shape. Dust the string or pipe cleaner lightly with sugar. The prepared surface gives crystals somewhere to begin forming.
- Suspend it in the jar. Lower the stick or string into the jar. Use a clothespin or clip to hold it in place, centered and clear of the jar’s sides. It should not rest on the bottom either.
- Cover the jar loosely. Keep dust out while allowing the jar to remain loosely covered. Leave it somewhere level and undisturbed. Check quietly every few hours or once a day; frequent handling may disturb the setup.
- Harvest when the crystals feel sturdy. Lift the stick or string slowly. If you want a cleaner look, rinse the crystals briefly with cool water. Handle them gently so the growing surface does not break or shed crystals.
- Dry the crystals. Place them on parchment or hang them to dry. Letting them dry fully helps reveal their small, glassy facets.
- Store the finished crystals. Once dry, place them in a dry, airtight container to help keep them crisp. Keep the container away from moisture.
Notes
Plan to supervise children around warm water and glass jars. Each jar may develop differently; wait until the crystals feel sturdy before harvesting. The project does not use yarn or crochet hooks.
