If you've been following this blog for a while, then you probably already know
the answer (and the explanation) to the following question: if you hold on to one end of a slinky and let the other side hang down until it stops moving, what would happen to the bottom end exactly when you let go of the top? Does it move up because the spring is no longer being stretched? Does it stay still? Does it fall because gravity is pulling down on it and there's nothing holding the slinky any longer?
