Okay, let's see how good your intuition is. The diameter of the Earth is 12,750 kilometers. It's pretty big. Now, let's say I take a piece of string and I go all around the Earth along its diameter, and that's the length of string number one. Now I take another string and I go around the Earth, but now I am lifted up from the ground by one foot—12 inches. Twelve inches above the ground, I go all around the Earth. That's the length of string number two.

How much longer is string number two compared to string number one? Is it longer by some feet, or is it longer by some kilometers? What does your intuition say? Quickly write it in the comments. How much longer is string number two compared to string number one? Is it longer by a couple of feet, or is it longer by a couple of kilometers?

Let me know in the comments. Bye.
