Why can’t you see the wind?

I wondered why you would ask that question. Maybe it is because you can feel the wind. So why can’t you see it?

The answer is so simple that it isn’t much fun. You can’t see the air around you. And wind is only moving air. So you can’t see the wind, either.

Maybe you would like to turn the question around. If we can’t see the air, how do we know it’s there? Because we can feel it when it moves as wind. If there were no air, planes and birds couldn’t fly—and you couldn’t breathe.
