In the last year alone, Crash Course was viewed 143 MILLION times. That's a lot of learning! And each video is worked on by 20+ human people who are absolutely devoted to quality and integrity. This has always only been possible because people like you believe that good information is worth us. Right now you can help keep Crash Course free for everyone forever at crashcoursecoin.com, and get a beautifully minted coin with your tax-deductible donation. @hankschannel @BadNaturalist
