The Strongest Man in the World Can’t Break this Egg!


Do you think that you are pretty strong? Is your father or mother strong? When you think of eggs, you probably don’t think that they are really strong, do you? In fact, you probably think that they are pretty weak, because if you drop them, they always break and make a big mess.

This science fair project is easy for students in kindergarten and first grade to do. Usually, science fair projects want to prove that a hypothesis is right (or wrong). For younger students, this can be too difficult to do. Here is the question that you are going to answer in this project: can you break an egg by squeezing? Can your mother or father break an egg by squeezing it?

The process of this science fair project is pretty easy. The equipment is something that you have in every kitchen: eggs and a bowl. The first step is to inspect the eggs to check and see if there are any cracks in them. Eggs that are cracked should not be used. To see if you can squeeze an egg, place it in the palm of your hand and close your fingers around it. Then squeeze it as hard as you can (over the bowl, of course, so you don’t make a mess all over the kitchen). What happened? Were you able to squeeze the egg and break it?
Repeat the experiment asking people who are stronger than you (and who have bigger hands) to give it a try. Could they squeeze the egg and break it?

If you are doing the experiment right, you shouldn’t be able to squeeze the egg and have it break. The reason why is that unlike what we believe, eggs are really quite strong. When thinking about how a chicken lays an egg, you can see that they are squeezed a lot, but don’t break.

Taking the same eggs that you tried to squeeze, break it (over the bowl). How did you do it? You probably tapped it against something, making a crack in the egg, and then were able to break the egg.

The structure of the egg makes it very strong, and unless you break the structure, even the strongest man in the world (or the person with the biggest hands) can’t squeeze an egg enough to make it break.

So was your answer to the question on whether or not you would be able to squeeze an egg right? Since you have been playing with eggs, you should make sure to wash your hands with soap and water to prevent some of the bacteria and viruses that can be found in uncooked eggs. After that, you may want to ask your mother or father to cook omelets for dinner.
