Air is a gaseous substance that encompasses our entire planet, Earth. It is well-known to nearly all living beings (except for the ones who live under rocks, of course!).
Air is made up of a mixture of gases that are absolutely essential for life, but it’s also filled with a bunch of stuff that can make us feel quite uncomfortable when we start to think about it. For example, air contains trillions of microscopic particles of lint, human skin cells, and even some dust bunnies that you forgot to sweep away.
Despite this gross nature, air is still really important. Without it, we would all suffocate like a frog under a rock. But in its current form, it can also be incredibly irritating. In fact, when you accidentally breathe in a fly or choke on a piece of food, it’s really just air playing tricks on us.
Air has many features that make it great to study. Scientists of all different kinds are fascinated by air, from physicists who study its properties, to meteorologists who figure out how it can control the weather, and even musicians who use it to create woodwind musical instruments.
But watch out though, air has a sinister side too! It can carry pollen that makes your eyes water and your nose itch, and, if you aren’t careful, it can also create disastrous hurricanes that can lift a whole cow over a house.
In conclusion, air is both amazing and terrible at the same time. So the next time you breathe in deeply, think about all that’s going on inside your lungs, and the many different particles and gases that make up this mysterious substance we call air.
