Just because you’re little and fuzzy doesn’t mean you can’t be nuts. These hamsters are determined to prove it.
Consider two things. 1) If a human being, like a hamster, were to run so fast that the camera could only record his legs as a blur–just how fast would he be going? And 2) why don’t these shenanigans on the wheel make hamsters desperately dizzy? That’s probably something NASA should investigate!
