Eureka: Season 2, Episode 5

2 - 5: Duck, Duck Goose

Space junk is massing over Eureka, forming a giant debris cloud that threatens to destroy the town and its inhabitants. Carter must find what is drawing it, and why, before disaster strikes. At first, they suspect a scientist who tried to use space junk as a weapon. Then, at the high school science fair, Zoe messes with a rival's project, an array, and all metallic things are drawn to it. They discover that an array of also similar design is on top of GD, it is used to take deep space photos. It was made by the mother of the student who created the smaller, original version. When the array bounces off of the electromagnetic shield around GD, it creates one giant magnet. The scientists at GD are able to make the space junk dissolve in the atmosphere.
