High voltage hi-jinks – our team of brainiacs gets to grips with electricity. We scientifically measure how much better looking women become after a couple of pints. Crackpot scientist Dr. Bunhead meddles with liquid oxygen. Tossing a salad, the lazy man’s way. We find out what goes on inside your stomach. After trying our carbon dioxide vehicles on land and water, now we try the sky. Does it cost less to send a parcel if it’s filled with helium balloons. What is the largest paper plane that will actually fly. Does a tooth dissolve if it’s left in a glass of cola overnight. Can you learn while you sleep. Former specialised debt collector Dave Courtney tackles our safe. And Fat v Thin continues.
