Science game show. Two teams of contestants compete to win a wheelbarrow-load of prizes. They need to use all their powers of reason and logic as they answer questions, perform scientific experiments, predict the outcome of jaw-dropping stunts and battle to win prizes in a furiously messy final game. While the winners go away laden with goodies, the losers have to blow theirs up. The theme is the strength of structures and weight distribution. In the Blast Lab, the two teams go surfing, but there are no waves, just cardboard tubes. The teams have to decide how to distribute these tubes to allow all three team members to surf without the tubes collapsing. Meanwhile, at Richard's secret test facility, the Lab Rats are attempting to build a bridge out of paper. Will it work or will it end in disaster?
