Richard Hammond’s Brain Reaction

Comedy Central, 9pm

What’s more powerful, a rugby player or a fireman’s hose? And what’s fastest, a Slinky going down a flight of stairs or a student downing a pint? All will be revealed in this comedy science panel show in which captains Victoria Coren Mitchell and Johnny Vegas battle it out over a series of conundrums. Tonight’s guests are Henning Wehn and London Hughes.
