Multiple dishes can also be incorporated into one plastic container to create a "multi-well plate". While glass Petri dishes may be reused after sterilization (via an autoclave at

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
