Envy Rots!




  • 1 glass
  • 1 white egg
  • 1 can of Cola



  1. Dip an egg in a glass of Cola and see how Cola damages the shell. Do the experience the day before in order to show it to the children.
  2. Re-experiment in front of the children and show them the final product (the egg that soaked overnight).
  3. Ask the children to try brushing the egg with toothpaste to remove the stain that is on the egg.
  4. Use discussion questions to explain that even though Coke tastes good, it has damaged the shell. Explain that when we envy “things” or people, it can rot the attitude of our hearts, just as the cola will rot the shell. If you leave the egg in the Cola for longer, the Cola eats away the shell. Envy is a bit like sugar that gives us tooth decay.
