Building the Perfect Squirrel Proof Bird Feeder

Mark Rober took up birdwatching as a hobby. However, squirrels discovered his new bird feeders. So, handy fellow that he is, Robert constructed an obstacle course to make things more difficult. But it's not just an obstacle course; it's more involved than anything you'd see on American Ninja Warrior. He even designed a photo opportunity in the middle of it! Yeah, the video is long, but you can skip to 7:40 and see squirrels trying to negotiate the course. Watch from the beginning to see how he built it. (via Gizmodo)
