Slinky = Sorcery

DrB

 

Reality is weird! Most noticeably so, when it comes to how gravity works on a slinky.

If you keep your eye on the bottom of the Slinky, on the last curl at the very end, you will notice that as the top of the Slinky starts to fall, the bottom doesn’t drop. It just hangs in the air, levitating, as if it had its own magic carpet. It will stay there, hovering quietly, until a wave, or signal, passing through the Slinky finally reaches it. Apparently, the bottom doesn’t know it’s supposed to fall, so it sits there, seeming to defy gravity, until the very end.
