You might want to grab some Eggland’s Best eggs because you need some health in your diet. Or you might choose to score some eggs not for eating, but for science. No hard-core research or anything like that. I’m talking elementary school science experiment stuff here.
OK, so get yourself one EB egg, preferably a pink ribbon egg.
And a glass.
And some vinegar.
Now, gently place the egg in the glass, and pour in the vinegar, until it completely covers the egg. Take a peek at the pink ribbon on the egg, because in a day or so, it won’t look the same!
After about 24 hours, remove the egg, and check out what happened: Your egg should be completely soft. Puncture it, and the egg will run out intact, but the shell will have become rubbery. And that pink ribbon? Probably gone or morphed into a pink smudge.
Here’s the science behind this experiment: Egg shells are made up of calcium carbonate, and the vinegar is made up of acetic acid. The acid dissolves the shell, and calcium ions float way from the egg into the vinegar while the carbonate turns into carbon dioxide — this is why you’ll see bubbles forming on the egg.
My 9-year-old Joey won’t eat an egg (picky eater!), but he loved this experiment. Easy enough that he could do it completely on his own — twice.
