The egg insides remain intact and are held together by the two fragile membranes just inside the shell."
And guess what? I could do this at home!!!
I grabbed an egg, put it in vinegar, and soon bubbles started forming on the shell.
After a few hours I could see parts of the shell floating on top of the vinegar as it dissolved. The shell itself was slimy whenever I poked it, from the shell dissolving. It was so cool!
14 hours later (at 5 am, yes I was up at that time for a short while getting Zach out the door to work) I carefully poured out the vinegar, and rinsed the egg under running water. I was left with a thin layer of white that still needed to dissolve. So back into the cup it went with some fresh vinegar.
4 hours and 45 minutes later it was ready to be carefully rinsed off, it was where I could carefully rub off the rest of the white stuff. I could start to see the membranes, and yolk and such. It was slightly squishy. It was soo fun!! But I rubbed too hard and it burst in my hands as I was rinsing it. Sad sad day!! The egg whites all went down the drain but I was able to catch the yolk (which was fun to slighly squish before breaking it, so I guess it wasn't a total loss. But then again I am easily entertained) and hang on to the membrane.
I am determined to make this work. I am going to be revisiting this one in the future. I am just going to wait awhile, because I need to save what vinegar I have for other purposes. I'll let you know when I get this working. Supposedly you can bounce the egg (lightly), you can color it, you can shrink it, and then regrow it. It is gonna be pretty awesome!
