Boyle's Law, named for Robert Boyle , the 17th century scientist who first published about it, is a description of the relationship between the pressure and volume of gas in a container given the temperature remains constant.
Your eyes might have just glazed over, but you already know all about Boyle's Law, and this is why you need physics class to put a name to what you already found out when you popped your first balloon.
Sometimes science is just a way of making connections between what you know and we know, collectively. Boyle's Law says there's an inverse relationship between the volume inside a container filled with gas and the pressure that gas is under. For instance, say you blew up a balloon only about half full of gas — in this case, the gas is the mixture of water vapor and carbon dioxide that comes out of our lungs when we exhale.
In the half-full balloon there's plenty of space for all those gas atoms to bump around without crowding any of them very much — the balloon itself might be pretty floppy. However, when you pinch all the air into one end of the balloon, the part of the balloon that has gas in it becomes taut.
