Daredevil science geek Greg Foot is prepared to attempt anything to find answers to some of life's weirder frequently-asked questions. In this episode, Greg suffers to find out what humans taste of, heads to Reading Festival to work out whether the human race could actually shift the planet by jumping at exactly the same time, and finds out whether a bellyflop could kill you.

Greg discovers whether there's any truth to the urban legend that you could survive in a falling lift if you jump as it hits the ground. He is prepared to sacrifice his friends in an eye-watering expose of what makes chillies hot and, with the help of a human substitute, he finds out what happens to our bodies when we die.

Self-confessed science geek Greg Foot squares up to champion cage fighter Rosie Sexton and friends to discover if winning unfair fights only happens in the movies. He asks why the sky is blue, probes the urban legend that your eyeballs fall out if you sneeze with your eyes open and experiences the highs and lows of surviving on your own bodily fluids.

Self-confessed science geek Greg Foot finds out if, like Uma Thurman in Kill Bill, you can escape after being buried alive. He also discovers what he needs to become the fastest man on the planet; works out why a boomerang comes back; finds out why bulletproof vests are actually bulletproof; and discovers whether water drains out of the sink the other way in Australia.

If a penny falls off the top of the Empire State Building and hits someone on the pavement, will it kill them? Science geek and adrenaline junkie Greg Foot risks his neck to get to the bottom of such things. Greg is also immersed in cold water to discover what extreme temperature can do, has his fingers hammered to test a weird painkiller, and investigates spontaneous human combustion.

The last episode sees self-confessed science geek and adrenaline junkie Greg under pressure as he and an inflatable friend attempt to dig to Australia. He is sucked into quicksand to discover if it is as deadly as the movies make out and he eats a stupefying amount of fast food to see just how quickly you can get fat without really trying.
