balls on chains

click click click...

You know what I'm talking about? Those little lets of (usually) five balls on a rack, suspended by chains... When you pull one ball on one side, it starts this whole series of reactions... the ball on the opposite side bounces in reaction... and it continues that way until you nearly reach the end, and all the balls are bouncing this way and that, not quite knowing which way to bounce... and that's when somebody pulls the ball at the end again... and again... and in the end you have a huge jumble.

My parents are beautiful people. But for some reason we don't seem to have any catastrophe control and support mechanisms in our family.

Don't know what to do.
