Episode 2

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 teams use Archimedes's principle of buoyancy to determine whether items will float or sink. Meanwhile, the Lab Rats, on a rare daytrip, attempt to build a cardboard boat for a relaxing trip down the river. Will they succeed or will the Lab Rats have to flee a sinking ship?
