A neat experiment to do with your eggs:

    Extra eggs laying around and some curious kids?
    Try this egg-speriment: [​IMG]
    First, take a normal, uncooked egg and set it in a dish big enough to hold the whole egg. Fill the dish with vinegar until the egg is submerged. Leave overnight.
    When you wake up in the morning, the vinegar will have dissolved all the calcium of the eggshell and you will be left with an egg encased by a membrane only!
    To go even furthur:
    To illustrate the permeability of an egg's membrane, take your now shell-less egg and immerse it in a dish of water for another night. When you wake up, the egg can easily double in size because of the water that it has soaked up! The egg is now huge and wobbly like a water balloon!

    We did it in highschool biology. You can also put the eggs in other solutions. In saltwater they will shrivel up.

    Sort of related, put a gummy candy (bear, worm, whatever) in water overnight. They, too, swell to double their size.

    Quote:That makes sense, because salt attracts water. the water would move out of the egg, into the salt water.

    That's why brining lean meat in very strong brine helps keep it from drying out when it's cooked. The salt in the meat keeps the moisture in the meat. But if you boil very lean meat in salty water, (when the meat hasn't been brined before cooking) the meat will become dry and stringy. The salt water draws the remaining moisture out of the meat.

    Great post! Bill Nigh the Science Guy would be pleased!
