No reviews

An engaging kitchen science experiment for kids to grow sugar crystals using simple ingredients and patience.

Ingredients

  • Granulated white sugar
  • Clean glass jars or heatproof glasses
  • Wooden craft sticks or a clean pencil
  • Cotton string or fishing line
  • Small clothespin or tape
  • Medium-sized pot for heating water
  • Measuring cup and spoon
  • Food coloring (optional)
  • Flavor extracts like vanilla or lemon (optional)

Instructions

  1. Warm the water slowly until it feels comfortably hot.
  2. Stir in sugar a little at a time until no more sugar dissolves and the liquid looks syrupy.
  3. Let the mixture cool slightly, then pour it into a clean glass jar.
  4. Tie a short length of string to a pencil or stick and dip the string in the solution.
  5. Suspend the string in the middle of the jar without touching the sides.
  6. Place the jar somewhere undisturbed at room temperature.
  7. Observe tiny crystal points forming each day.
  8. Add a drop of food coloring once the solution cools, if desired.
  9. After several days to a week, lift the string to admire your crystals.
  10. Store finished crystals in a dry place.

Notes

Be cautious with hot water; adult supervision is required when using the stove. If crystals stick to the jar, run the jar under warm water to loosen.
