I swear, this is the coolest thing ever... I had to make deshelled eggs for one of my classes. I had never done if before. It is so cool! If you have never done it, you have to do it just to see how interesting it is. All you do is place a raw egg fully submerged for 24-48 hours in vinegar (I just used regular white vinegar). The shell will slowly start to dissolve away. One of mine only took about 24 hours, but the other took close to 48. Once you can see that the shell has mostly dissolved, you can take the egg out and rinse it off. You are left with an egg just held together by the membrane, no shell. They almost don't even feel like real eggs! They have sort of the consistency of a rubber ball. Go try it! You will be so glad you did!
