How to Make Sugar Crystals?

Are you looking for ways to make sugar crystals? If yes, we can help you teach how to make sugar crystals using the materials easily available at home. Kids would enjoy performing experiments to make sugar crystals. This will help them learn about the science behind the formation of sugar crystals. Conducting science experiments for kids enables them to observe and analyze the changes to come up with logical conclusions. This is one of the best DIY science project ideas for kids in the school curriculum. 


Can you make sugar crystals at home? Yes, it is an extremely easy and fun experiment for kids. It is better if kids carry out this experiment under the supervision of elders to get accurate results. You can conduct science experiments for toddlers, preschoolers, kindergarten and elementary school kids by unfolding the magic of making beautiful sugar crystals in front of their eyes. You can check out how to make sugar crystals mentioned in this article. 

Easy Science Projects: How to Make Sugar Crystals? 

Have your children eaten rock candies? How do you make them? You can prepare them from the crystallization process. When the sugar syrup freezes into ice, it becomes sugar crystals. You can teach kids the process of supersaturation and crystallization, the mechanism behind sugar crystal formation, by conducting this simple experiment effectively. For that, you need nothing but materials easily found at home. Read on to find out the sugar crystallization process from the experiment given below.

Aim of the Project 

The aim of this project is to perform an experiment and observe how sugar crystals are formed using the materials available at home under the supervision of elders. 

Materials Required 

  • A cup of boiling water 
  • Two cups of sugar
  • A glass 
  • A stick 
  • A piece of thread
  • A few drops of food coloring liquid
  • An aluminum foil 


  • Take a cup of hot boiling water and pour it into a glass. 
  • Add two cups of sugar to the boiling water. 
  • Add a few drops of food coloring liquid. 
  • Stir it well until it dissolves completely. 
  • Take a stick and tie a piece of thread in the center. 
  • Keep the stick on the glass so that the three-fourths of the thread is dipped inside the sugar syrup.
  • Cover the glass with aluminum foil, leaving some air to cool down the sugar syrup. 
  • Keep the glass for a week without disturbing it. 
  • Observe and record the changes after a week.


In this experiment, kids observe that the sugar crystals are formed around the thread dipped inside the sugar syrup. When the temperature decreases, the sugar comes out of the solution to form crystals. The difference in the ratio of solute and solvent creates supersaturation of the solution. 

Also, explore how to separate salt and water.
