This video, from Tom Scott, talks about the history of what is the most expensive object in the world by weight. It is very small and very expensive.
More importantly it is ‘non-fungible’ – things means it cannot be split up into smaller parts and keep the same value.
In this lesson students discuss the things they own. How the history of an object is important and if they collect anything. The PDF has comprehension and discussion questions and transcript of the video with answers highlighted. This video is definitely intermediate level English and above.
