In the Lab, the two teams use the convection created by hairdryers to keep bags in the air. Then, using great skill and dexterity, they have to negotiate an obstacle course. Out on Richard's secret test facility, the Lab Rats use the same principle to try and make a giant solar balloon. Will the sun's heat be enough to help their balloon lift up, up and away?
