Louis Pasteur's experiments with the S-neck flask involved air exchange through the curved neck, which prevented microorganisms from entering. A food source was provided for potential microorganisms to grow if they could enter. The design ensured that all preexisting microorganisms in the broth were killed through boiling, and the shape of the flask prevented airborne contaminants from reaching the broth, effectively demonstrating that spontaneous generation of microorganisms does not occur.
