Let’s Make Naked Eggs by Carolyn Presutti
A naked egg is an egg without a shell. Using vinegar, you can dissolve the eggshell without breaking the membrane that contains the egg.
Tools:
• a few eggs
• white vinegar
• a container big enough to hold all your eggs and a cover for the container
• a big spoon
1. Place your eggs in the container so that they are not touching.
2. Add enough vinegar to cover the eggs. Notice that bubbles form on the eggs. Cover the container, put it in the refrigerator, and let the eggs sit in the vinegar for 24 hours.
3. Use your big spoon to scoop the eggs out of the vinegar. Be careful—since the eggshell has been dissolving, the egg membrane may be the only thing holding the egg together. The membrane is not as durable as the shell.
4. Carefully dump out the vinegar. Put the eggs back in the container and cover them with fresh vinegar. Leave the eggs in the refrigerator for another 24 hours.
5. Scoop the eggs out again and rinse them carefully. If any of the membranes have broken, letting the egg ooze out, throw those eggs away.
6. When you’re done, you’ll have an egg without a shell. It looks like an egg, but it’s translucent—and the membrane flexes when you squeeze it. Very cool!
Remember to use a towel on the table when you allow your kids to "play" with the naked egg. Kids find it irresistible to not squeeze the egg. Have fun!
