Festival Of The Spoken Nerd

The purple cow is back at the Southbank with a bellyful of scintillating circus, side-splitting comedy and fantastic family entertainment for you this summer, along with one of London’s biggest outdoor bars.

The science comedy phenomenon returns, and this time they're off the chart. Join acclaimed stand-up mathematician Matt Parker, experiments maestro Steve ‘Danger’ Mould and geek songstress Helen Arney for graph-a-minute fun on an unprecedented linear scale.
