In this episode of Check It/Round Table Onna discusses the Youtube Channel, Knowing Better, https://www.youtube.com/channel/UC8XjmAEDVZSCQjI150cb4QA, which Onna discovered from an ESL student (thanks Riel;)!).  Onna considers how this channel features many interesting videos on history, science, and current events (such as how most of us can't really see 4K, for example).  It's all here.  It's all real.
