Homemade slinky staircase is the pinnacle of human ingenuity

Not content with just watching a slinky toy walk downstairs, Matthias Wandel invented the perfect slinky-only escalator.

Wandel’s slinky machine was carefully tested to be the right size and speed for a slinky toy, allowing the slinky to drop from stair to stair indefinitely. The building and testing process looks like it took a lot of work, but the end result is oddly mesmerizing.

This is human ingenuity right here.

Pointless? Yes. But still undeniably satisfying to watch.
