I haven't tried this yet, but I can't wait to see if it works! Write secret messages on hard cooked eggs - messages that appear only when the egg is shelled and ready to eat. You put the design on the eggs BEFORE they are cooked.

Ingredients Nutrition

  • 12 eggs, raw (or as many as you want to use)
  • 1 ounce alum
  • 12 pint vinegar


  1. Dissolve the alum in the vinegar.
  2. Use a small paint brush to write messages or draw designs on the egg shells.
  3. Let the solution dry thoroughly.
  4. Boil the eggs as you usually would.
  5. ***There will be no trace of writing on the shell when the eggs are served, but inside on the hard-cooked egg white, the writing or design will appear bright and clear.

DO NOT TRY. No offense, but this simply did not work one iota. Too bad. Fortunately, I had the presence of mind not to tell the kids about my experiment.
