Vsauce is an educational YouTube channel that introduces “mind-blowing facts” (see the about page) about science, technology, culture, and various other topics. It won a Webby People’s Voice award this year for best news and information. Most of the videos have links to related sites, to further satisfy your curiosity.
Just a few examples:
“Will We Ever Run Out of New Music?”
“Why Are Bad Words Bad?”
“Where Do Deleted Files Go?”
