1. Take a regular egg and write your name on it in crayon.
2. Place the egg in a bowl full of vinegar and let it sit for an hour or two, until the vinegar stops bubbling.
3. Replace the vinegar with a fresh supply and let the egg sit for another four hours. The vinegar has been eating away at the eggshell except where the crayon was used.
4. Remove the egg and very carefully, scrub the egg with a dishwashing brush to remove the crayon. Your name will look like it was carved in the eggshell!
