Petri dish be used to observe plant germination, the behavior of very small animals or for other day-to-day laboratory practices such as drying fluids in an oven and carrying or storing samples. Their transparency and flat profile also mean they are commonly used as temporary receptacles for viewing samples, especially liquids, under a low-power microscope. Petri dish A Petri dish (sometimes spelled "Petrie Dish" and alternatively known as a Petri plate or cell-culture dish), named after the German bacteriologist Julius Richard Petri, is a shallow cylindrical glass or plastic lidded dish that biologists use to culture cellssuch as bacteriaor small mosses.

The Dish service a backup generator, putting their part in the mission at risk. They apply all their science skills to reacquire the signal and cover their mistake, so that everything works out in the end. The directors of the film portray, quite accurately, what is in essence, a complex technical task, such as re-pointing the dish when it loses the signal's "lock" and deciding to use it when the wind whips up threatening to damage the structure. The film dramatises the team-work of a few technicians, who sometimes nearly lose their tempers with each other, painted against a backdrop of proud
