Say I have a ball, but this ball is bound by special rules. I throw the ball in a pond, and it turns into a ripple. The ripple hits a stick, and it comes back up as a ball.
And say I take the same ball, and throw it against the wall, and every-time I do this, I run the risk of the ball going through the wall and not coming back.
How does this ball interact with others of its kind?
