Bang Goes the Theory
Dallas Campbell, Liz Bonnin, Jem Stansfield and Dr. Yan Wong take on the scientific world by devising their own ingenious ways of explaining cutting-edge developments in technology.

Jem faces his toughest challenge yet: to build a boat made out of ice, and take it and the rest of the team for a spin in one of the UK's busiest stretches of water. Dallas investigates the world of comets and tries to build his own, while Liz looks at the science behind hypothermia and gets repeatedly dunked into ice-cold water in preparation for the ice boat extravaganza.
