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 guide magnetic rockets out of the Magnet Maze, dodging comets and stars along the way. Then, in a game based on sound and pitch, Sam and Ayo play a tune using three hidden jars filled with different volumes of water. In the lab, Ayo dreams of inventing something spectacular, just like the famous scientist Leonardo da Vinci did. Inspired by the scientist's self-supporting bridge and designs for flying machines, will she come up with something the world has never seen before?
