Wonder why a cat always lands on its feet? It's a question that stumped scientists for over a hundred years. Some suspected that mischievous cats were breaking the laws of physics! Was it the catnip? Or was it a mystery of physics? Physicist Greg Gbur helps us break the case... with the first ever cat video. Check out the original flipping cat photos and film, as well as a video of cats weightless in zero gravity (!!) on our blog at sciencepodcastforkids.com. You'll also find visual explanations from Greg Gbur and YouTube channel Smarter Every Day. Want an ad-free version of Tumble? It’s only $1 each month.
