* Vinegar: Vinegar (acetic acid) can indeed dissolve the calcium carbonate shell of an egg. This is a slow process, but over time, the shell will weaken and eventually dissolve, leaving the egg's membrane intact.
* Nail polish remover: Nail polish remover usually contains acetone, which is a strong solvent. While acetone might damage the shell of an egg, it's unlikely to completely dissolve it. The main issue is that acetone will denature the egg proteins, making the egg tough and rubbery.
In summary:
* Vinegar will dissolve the egg shell.
* Nail polish remover will damage the egg shell and denature the proteins.
