We all have our favorite little pieces of this earth, but it's hard to take a step back and think about the whole planet. In honor of Earth Day, I wanted to pass along a little activity that is the closest I've ever come to being able to literally feel the whole earth move. It just takes a few minutes -- and it involves watching the sunset. So what have you got to lose?
Here's the trick. As you watch the sun cross the horizon, remind yourself of this:
You're not watching the sun move. You are spinning with the earth.
I know you learned this in grade school. But try really watching it happen. Sunset tonight is at 7:52.
Let us know how it went!
