Returning for 2026! Brace yourselves for BBC Gastronaut Stefan Gates’ revolutionary, high-tech, highly explosive show, Rude Science, packed with outrageous science stunts. On the surface it’s a riot of disgusting experiments built to delight young audiences but under the bonnet it’s a brilliantly constructed curriculum-driven adventure designed to inspire Britain’s kids with a lasting fascination for science. Expect enormous bottoms, frt machines, snot cocktails, vast whoopee cushions, pee-powered fireworks and ear-wax-oozing mannequins. Stef is the high-octane presenter of 20 TV series (five for CBBC) and award-winning author of 12 books (including Rude Science). He’s internationally renowned for his world-class science stage shows.
