Can horses feel electric shocks through their fur? Can we create lightning artificially? How do we send electric signals via cables to America? Can frozen nitrogen conduct electricity? We tackle these sparky questions on this weeks show. We also learn about the northern lights, reveal why rain falls heavier than snow and investigate if it really is dangerous to pour hot water into a glass.
