Never-mind the science, the naked egg activity is loads of fun for kids and for parents, too! This demonstration has you take the shell off an egg without breaking it! It’s amazingly simple to do…
- Raw Egg
Fill a cup with vinegar, and carefully put a raw egg inside. Keep an eye on it for 3 days. On the third day, the shell should be completely gone, and there should be a bouncy ball of egg in the cup!
Explain that the membrane that is left is a lot like the one in a mommy’s tummy when she has a baby inside. Just like the egg membrane protects the chick inside the egg, the sac in a mother protects the baby inside her.
This membrane is actually very strong, and you can bounce it like a ball, although we do not recommend dropping it from too high!
