Two teams touch down at the STARS space station to take on three scientific challenges to win out-of-this-world prizes. First, they must decide whether objects will float or sink in a water tank. Then, in a game based on light and shadows, the young scientists have to figure out what their team captains are holding by observing their shadows behind a huge screen.\n\nMeanwhile, Sam and Ayo are competing to see who can make the best model rocket. The scientist who loses must clean the other’s dirty lab beakers for a week!
