Why is duct tape the answer to fixing everything? How do geckos cling to walls? And what, exactly, keeps our car tyres rolling down the road? In Sticky: The Secret Science of Surfaces, physicist and science writer Laurie Winkless paints a vivid picture of the vast array of surfaces we interact with every day – and explores the mysteries we’re still unravelling about how those interactions work.  We talk to Winkless about earthquakes and geckos, and discuss why even the things we sometimes take for granted (like that little broom they use in curling) have a fascinating scientific story to tell.
