Studio-based science game show set in the surreal world of Richard Hammond's secret laboratory. Richard explores the theme of fluid dynamics. In Mini Miss's science lesson, the two teams try to encase a team member, dressed as a hedgehog, in a giant bubble. Steely determination and patience are key to this game as they try to prevent the bubble from bursting on the spikes. Meanwhile at Richard's top secret test laboratory, his Lab Rats investigate the science behind bubbles. Richard asks if it is possible to a make a bubble large enough to cover a Lab Rat sitting in a bath surrounded by a selection of sharp objects, and finds out about the science of 'stretchy' water.
