Materials: 1 wooden skewer, 1 clothespin, 1 cup of water, 2 cups of sugar, 1 tall narrow glass or jar

Procedures

  1. Clip the wooden skewer into the clothespin so that it hangs down inside the glass and is about 1 inch (2.5 cm) from the bottom of the glass. (as shown)

  2. Pour the water into a pan and bring it to boil.

  3. Pour about 1/4 cup of sugar into the boiling water, stirring until it dissolves.

  4. Keep adding more and more sugar, each time stirring it until it dissolves, until no more will dissolve. This will take time and patience and it will take longer for the sugar to dissolve each time. Be sure you don’t give up too soon. Once no more sugar will dissolve, remove it from heat and allow it to cool for at least 20 minutes.

  5. Have your friendly ADULT carefully pour the sugar solution into the jar almost to the top. Then submerge the skewer back into the glass making sure that it is hanging straight down the middle without touching the sides.

  6. Allow the jar to fully cool and put it someplace where it will not be disturbed.

  7. Now just wait. The sugar crystals will grow over the next 3-7 days.

Conclution

After the first day nothing really happened then after I got home from school the next day I started to see some crystals growing on the stick. Once it was completely finished I was so excited to find out how it tasted because I love rock candy. It was so good and now I'm happy because I can make my own candy instead of having to go to the store and buy it!!!
