Wacky Laws from Around the World There are all kinds of unusual laws on the books around the world. Some of them are rarely enforced and have hung around because they’re not bothering anyone: -In Arkansas, it’s strictly prohibited to mispronounce the name of the state. -A law in the EU states that bananas must be free from malformation or abnormal curvature, known locally as the “bendy banana law.”

Laws of science describe things in the physical world that will always happen under specific conditions. For example Sir Isaac Newton discovered the law of gravity: The glass jar you accidentally drop will always fall to the floor (oops.) Sir Isaac Newton also discovered the law of inertia: An object’s speed won’t change unless another force acts upon it. That’s why your toys don’t move by themselves and why your car needs brakes to stop.

You can test inertia yourself. Take one raw and one hard-boiled egg. Spin the hard-boiled egg on its side. When it’s moving fast, very gently stop it, taking your hand away immediately when it stops. Then, repeat with the raw egg. The hard-boiled egg will stop when you let go, but the raw egg will start turning again, because the liquid in the egg is still moving. The gentle force from your hand was not enough to stop the inertia of the shell and the inside of the egg.
