  1. Cut egg carton bottom to hold desired number of egg shells.
  2. Wash eggshells gently in a mild soapy solution.  Rinse and pat dry with paper towels or let air dry.
  3. Using a teaspoon, fill each eggshell with up soil up to 1/2 inch from the top.
  4. Put shells in place in egg carton.
  5. Place 3 or 4 seeds in each eggshell.  Then place 1/4 inch of soil over seeds and gently pat down.
  6. When all shells have been planted, water lightly and place in a sunny window sill.
  7. Make sure your child waters each shell daily with a teasoon of water. (more if soil is drying out quickly)
  8. Once seedlings emerge they may be planted outdoors if it is warm enough in the season.  Or if this is a winter project, plant them in a pot to watch them grow indoors.  (Make a small hole in bottom of eggshell or crush bottom to allow roots to spread when planting.)
