Woobly, Wacky Egg
This is an ah-maze-ing experiment.
It’s one of those ones that doesn’t take much in terms of work or supplies but it does require patience. So practice that delayed gratification… I promise, this is worth it!
What you need:
– A glass
– One raw egg
& of course, one Wacky WhyNot experimenter (who brought her/his patience!)
– Put your egg in the glass and cover it with vinegar. It’s OK if it floats a bit, just get it pretty much totally submerged in the vinegar.
– Wait a long time (like 12-24 Hours long). It will bubble gently as the chemical reaction between the vinegar and the calcium in the egg goes to work.
– Gently lift out your egg and gently rub the shell. It will sort of flake away.
– If your egg isn’t totally shell-less, put it in a cup of new vinegar for another 12-24 hours. Repeat the gentle shell removal process.
At the end you will have your egg, just without the shell!
Clearly, it’s fragile, but it’s also amazing, interesting, funky, cool and wacky!
NOTE: don’t eat this egg. It’s been chillin’ in vinegar a long time.
– Take your newly shell-less egg and submerge it in a bunch of plain water. Wait + Watch it swell as the water goes through the egg’s membrane into the egg.
– Then let it hang out in REALLY salty water… you’ll get the equivalent of a raisin egg!
