Science game show. Two teams of contestants compete to win a wheelbarrowload of prizes. They need to use 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 must blow theirs up. This show looks at air pressure. In the Lab, the two teams play Cup on Your Face, which involves them carefully negotiating an obstacle course whilst transporting plastic containers stuck on their faces using the strength of suction alone. On location at Richard's secret test facility, the Lab Rats are finding out just how strong air pressure can be as they attempt to pull apart a Magdeburg pressure sphere.
