Make a sweet treat with your child this Valentines’ day while learning about the science theory of how the sugar crystals are form!

Why this happens:

Water molecules move slowly up into the air as water vapor during the process of evaporation. As more and more water evaporates, sugar atoms draw close together, forming cube-shaped sugar crystals. And that’s just what you’ll see left behind on the string after the water is all gone!

You will need:

  • 2 cups of water
  • 4 cups of granulated sugar
  • ½ – 1 tablesppon of flavouring extract or oil
  • Food colouring
  • Skewer or thread
  • Glass Jar
