What You Need:
- String - 15cm
- A pencil
- A paper clip (or large plastic bead)
- Water - 1 cup
- Sugar - 2 cups
- A glass jar
- Tie the 15cm string to the middle of the pencil.
- Tie the paper clip (or bead) onto the end of the string.
- Put the pencil across the top of the jar so that the string hangs down into the middle of the jar. If it hangs down too far, roll the string around the pencil until the string is not touching the sides or bottom of the jar. The string will act as a seed for the crystal. Now that the string and pencil are ready, remove them from the jar and put them aside. Ask a parent or adult to help you with the next three steps.
- Pour the water into a pan and bring it to boil.
- Pour about 1/4 cup of sugar into the boiling water, stirring until it dissolves. Keep adding more and more sugar, stirring it each time until it dissolves. Stop adding sugar when you find that no more sugar will dissolve. This will take time and patience so make sure you don't give up too soon.
- Carefully pour the hot sugar solution into the jar right to the top. Then submerge the paper clip and string into the sugar solution. Be sure the string hangs down in the middle of the jar.
- Allow the jar to cool and put it someplace where it will not be disturbed. In a week your jar would have accumulated large crystals.
