Do you know that the empty eggshells are actually a perfect environment for germination because they consist of calcium carbonate and a little protein? With mini potted plants in empty eggshells, the flower bed is both delicate and colorful. Make a dozen and you’ll have a home-made desktop mini garden of your own! You can also work with your kids to turn some of their colored eggs into a charming Easter eggshell garden. Enjoy!
