Apples rot and turn brown because they take in oxygen and give off carbon dioxide. If apples are stored in cool temperatures, they will rot slower than they would in room temperature. Other conditions such as humidity, and the storage atmosphere also effect how quickly apples rot.


  • Peel and core apples.
  • Carve faces into apples with a plastic knife.
  • Add 2 tablespoons lemon juice to two cups water.
  • Soak the apple faces in the mixture for 10 minutes.
  • Hang the apples to dry, running a string through the opening where the core was removed.
