Jim Sellers (Oregon, WI) built this lovely Slink-O-Matic Slinky-playing machine. Why? Why not? D’uh.

It “slinks” a slinky for you, at times when there are no stairs and you just have to…

Also useful in determining whether one is in the northern or the southern hemisphere. Due to Coriolis forces it will “slink” from right to left in the northern hemisphere and from
left to right in the southern hemisphere. ;-)

Why should The Most Useless Machine have all the fun?
