An egg soaking in vinegar with part of it’s shell dissolved.
![THE "NAKED" EGG
This is really cool! It will amaze your kids and teach them some science all at once.
Christina Haswell says: I did this for a science project when I was a kid about 20 yrs. ago n passed it on to my son when he did his science project last year. It's really cool! It takes about 4 to 7 days.
Put an egg in a cup and fill it with apple cider vinegar till egg is covered. Cover tightly n let it sit. Each day give it a swirl. At the end u rinse off the egg n VIOLA! A rubber egg! Just be careful...it will bounce but is still delicate. And very smelly when it breaks. LOL ...Not rotten -- just smells like vinegar. Always keep it in the fridge during the whole process too.
Stefany Smith added: If you place the "naked egg" in corn syrup, it will shrink/shrivel up. The vinegar inside the egg moves through the semi-permeable membrane.
You can then place it in water with food coloring and "color" the inside of the egg and it will fill up again due to osmosis
