Removing an Eggshell

1 Ziploc sandwich bag
1 uncooked egg
16-fluid oz. white vinegar
1 glass
1) Put the egg in the bag. Add enough vinegar to completely cover the egg, or enough to half-way fill the bag.
2) Close the bag, removing most of the air. Observe the egg, noticing specifically the bubbles on the shell.
3) Turn the bag so that the egg is in one corner, and place this corner into the glass.
4) Let the egg sit overnight. In the morning it will feel soft, this is because the vinegar has dissolved most of the hard part of the shell. Let the egg sit for 2 more days in the vinegar, to assure that the shell has been dissolved.
5) Over the sink, pour the vinegar out of the bag. Under a trickle of water, wash the egg gently to get all traces of the shell off. Explanation: The shell was dissolved by the vinegar, but the membrane underneath wasn't. The membrane helps protect the egg. Observe how the shelled egg feels.
