Redi's experiment demonstrated that only the broth with the flask open to the air contained living organisms. In his experiment, he used jars with rotting meat, some of which were sealed and some left open. He found that flies laid eggs on the open jars but not on the sealed ones, supporting the idea that external contaminants (like flies) were necessary for the presence of living organisms, thus challenging the theory of spontaneous generation.
