Let's explain gravity

A little memo to people who fire their guns in the air on New Year's Eve:

A bullet, as fast as it is, does not have what they call "escape velocity." That is to say, the bullet does not actually break through the atmosphere to enter our planet's orbit. Therefore, it will actually rise high in the air until gravity catches up with it's velocity. There will be a brief moment when it's velocity and gravity are tied, and it will float in mid-air. But that's just for a fraction of a second. After that, it falls back to earth. Really fast. Like it was, oh, let's search for a metaphor, shot from a gun. And then it'll hit the ground. Or a roof. Or the top of someone's skull.

Just in case you didn't know.

P.S. These last three posts stand as the three most sarcastic posts in this blog's history. Is there a trend developing here?
