About this episode

Professor Hannah Fry explores the science behind Moroccan mint tea with guest Michael Stevens, discussing fluid dynamics and environmental questions.

Does a teapot secretly hold the laws of physics? And what do soap, sugar and mint have to do with the perfect cup of tea? Whilst in Morocco, Professor Hannah Fry takes Michael Stevens (VSauce) into the surprising science of mint tea, from foamy bubbles that trap desert sand to the elegant S-shaped spout that appears to solve some of the hardest problems in fluid dynamics. Plus, your questions, including whether rising sea levels could change how your eggs boil, and just how much of Earth humans have actually touched. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
