Bompas And Parr

Sam Bompas and Harry Parr celebrate the launch of their new book, 'Cocktails with Bompas & Parr', with a demonstration on how they mix certain chemicals to fine (and tasty) effect. Since the pair began dabbling in 2007, they've invented breathable gin and tonics, flooded a grade one listed building and, most recently, created a bright green boating lake on the roof of Selfridges. Tonight is sure to be fun and every guest receives a Hendrick's gin cocktail. Booking essential.
