In Pasteur's experiment, the control was a swan neck flask that prevented air from getting in. This setup allowed Pasteur to demonstrate that microorganisms in the air were responsible for the spoilage of substances, as the flasks with the swan necks remained free from contamination while allowing air to circulate without direct exposure to airborne particles.
