If there’s one thing squirrels love, it's food; and they’re capable of remembering some pretty complex directions to get to it, too!
This video from England shows a squirrel traversing a variety of obstacles, similar to a Rube Goldberg machine, to get to a prized bowl of nuts. Apparently the owners constructed the machine a bit at a time, rewarding the squirrel with food at the end of each section. After about two weeks, the squirrel was able to make it through the entire machine. Very Ethan Hunt!
