Ever try the raw egg, still in shell, soaking in vinegar? It is so cool. You take an egg and put it in a sealed jar full of white vinegar, then sit back and watch. It is supposed to dissolve the shell and leave the inside of the egg intact. The vinegar won't dissolve the membrane inside so the egg is supposed to just like an egg but without a shell. I'm on day 2 and the vinegar is diffidently eating away at the shell. My 2 year old son thinks it is just amazing. In just the couple of hours, the egg was turning all over the place and has now floated to the top. You can see patches of very thin spot in the egg. If you have kids, you got to try this.
