Find out the strange science facts and ancient instincts which combine to encourage our desire for maximum pleasure in this evening devoted to hedonism. Find out how a search to relieve the pain of childbirth resulted in the invention of LSD, hear about a new theory suggesting that sound influences taste and explore the results of our largest ever national survey of sexual habits. Regular Lates activities such as Sensory Speed Dating, Punk Science (£5 - book in advance), the pub quiz (£2) and a silent disco will all be going on, too. In their most extravagant forms, of course. Admission and most activities are free.
