The team looks at advances in food science and technology, and the world's one and only vegetable orchestra, led by Teddy Clarke, gives us a live performance in the studio. We meet Andy Gough, Slimmer of the Year, a fellow who lost fifty-two stone [for American viewers: one stone is sixteen pounds] in six weeks, thanks to a controversial slimming powder. We also visit the food industry's annual show and see some inspiring hi-tech developments. A special report looks at the growth of fast food casserole joints, stepping into the world's only computer-run casserole cafe where the menu features four types of casserole - beef, chicken, ham and porcupine. Lastly, the gang throws a futuristic birthday party for Pam - with a surprise guest.
