Find a large bowl or rubbish bin and a few raw eggs.
Making sure they have no rings on their fingers, ask your friends or family to take one of the eggs in the palm of their hand and gently wrap their fingers around it. With their hand held over the bowl or bin, ask them to try to crush the egg. They won’t be able to!
As the pressure from their hand is spread over the whole surface of the egg, crushing it should be impossible. But, make sure to have a towel ready in case something goes horribly wrong. You don’t want to be left with egg on your face!
How does this work? The structure of an egg is designed in such a way that it can withstand incredible forces. When you place the egg in your hand and squeeze, the pressure over the egg is distributed evenly and the egg remains intact. When you apply the pressure or force in one particular place the egg cannot withstand it. It’s a good thing those little chicks (baby hens) have a tiny beak to peck their way out! |
