        Here’s an experiment that turns a hard eggshell into a slimy soft covering - and then you can make the egg shrink and swell. This one’s amazing! To remove the shell from the egg without touching it: Place an egg in a glass and cover it with vinegar. Look closely and you’ll see bubbles appear on the shell. This is carbon dioxide - the same gas that makes soda bubble. Carbon dioxide is released when the vinegar reacts with the shell. Let the egg sit for three days. Most of the shell with dissolve. Carefully pick the slippery, squishy egg out of the vinegar with your fingers. The egg will look like a small water-filled balloon, and you’ll be able to see the yolk clearly. If little bits of soft shell material remain, gently rinse the egg under a trickle of water. Shake it carefully and let the kids feel the egg without its shell. Now you’re ready to shrink the slippery egg. Put the egg in a clean glass and cover with white corn syrup. Let it sit overnight.

        In the morning, fish out the egg with your fingers and rinse it off. The egg will look smaller, and you should be able to feel the lump of yolk. Overnight, much of the water inside the egg passed through the egg’s porous membrane into the corn syrup. (Corn syrup is too thick a substance to have passed through the membrane into the egg.) As a result, the egg shrank. If you want, you can reverse the process. Place the egg into a glass of water and then let it sit overnight. By morning, the egg will have swelled up again. This time, the water passed through the membrane back into the egg. Who said science is boring?!
