Inside a cow’s stomach, especially the rumen, microbes break down grass and other fibrous food through fermentation, producing methane gas as by-product. In a floating cow model used in water exhibits or science displays, the gas (or simulated gas) is released through a vent or outlet to mimic cow burping, which is the
