We travelled the sea far and wide. At one time, two of my sailors were standing on opposite sides of the ship. One was looking west and the other one east. And at the same time, they could see each other clearly. How can that be possible?
The sailors had their backs against either ends of the ship.
Only one color, but not one size.
Stuck at the bottom, yet I easily fly.
Present in sun, but not in rain.
Doing no harm, and feeling no pain.
What Am I?
