You would have to be pretty bored to come up with this one. This guy had nothing better to do so, he put a Slinky on a treadmill to see how long he could get it to 'walk'.  He had seen something that talked about the record for a Slinky on a treadmill being about 22 seconds or so.Again, with nothing better to do and obviously no prospects of something better, he put his Slinky on his treadmill to try and break that record. He even put some very dramatic music behind it for effect. Well, the Slinky is able to stay on for over three minutes! I don't know if this is a world record, but it's kinda cool to watch if of course, you have nothing better to do.
