Richard Hammond's Brain Reaction S01E06 - Robin Morgan, Thanyia Moore

In this riotous series finale episode, Victoria Coren Mitchell and teammate Robin Morgan pit their grey matter against Johnny Vegas and Thanyia Moore. And keeping proceedings scientifically relevant is comedian and clever woman Ria Lina.

The science of swallowing comes under forensic scrutiny in: How many hot dogs can you eat in 30 seconds? Johnny and Victoria experiment, somewhat reluctantly, with iced water, needles and electricity in a test of their dexterity. Thanyia and Robin show off their pumping action skills to find out what can take the most pressure. And in an explosive ending, the teams deconstruct a hipster's breakfast to discover if it's dangerous or just plain irritating.
