This week, a banana sold at auction for $6.2 million dollars. Well, not quite… it’s actually a piece of conceptual art and it’s WAY more than just a banana. There’s also some duct tape. In response to this most bananas of auctions, the Unexpected Elements team are going bananas for bananas! We investigate the science of slipping on a banana-skin. Is it just ‘cartoon physics’ or are they actually a slip-hazard? And did you know your breakfast banana might be… radioactive? Also, can Romanian ethical hackers succeed where the police have failed? We look at the computer sleuths tackling real life missing persons cases. We find the answer to why toads have evolved such dangerous skins, and yet more bananas, as we look at the pros and cons of the Ethiopian False Banana. Why hasn’t this hardy plant conquered the world? Presenter: Marnie Chesterton, with Andrada Fiscutean and Christine Yohannes Producers: Emily Knight, Alice Lipscombe-Southwell and William Hornbrook Sound engineer: Searle Whittney
