Helium is a very common element in our universe. However, due to its characteristics, it's very rarely found on Earth. This video shows how scientists in the 19th century overcame this obstacle, over the course of decades, and isolated and discovered the rare gas. Hosted by Simplecast, an AdsWizz company.
