Looking at the Slink-O-Matic, you might think to yourself, "Now there's one pointless invention." You would be correct in thinking this, except there is a point to it beyond the fact that is simply plays with a Slinky for you.

Designed by Jim Sellers, the Slink-O-Matic can actually determine which hemisphere you occupy. According to the inventor, "Due to Coriolis forces it will "slink" from right to left in the northern hemisphere and from left to right in the southern hemisphere."
