Why is our peripheral vision so good in the dark? Why do we have goosebumps? Do UFOs exist and is there life on other planets? We explore the answers to these questions as well as investigate how bacteria know where to infect us, how our TV screens work, why we set our clocks back in winter and reveal if covering our bodies in salt would make us shrivel up like a slug!
