Commonly found in cow dung, the tiny fungus Pilobolus has a unique way of spreading its spores. In order for the spores of Pilobolus to get away from its smelly dwelling, to land on some tasty grass that will lead it back into the stomach of a cow, the fungus uses propulsion to launch itself to a relatively far distance of nearly 10 feet. For the spores to get to such a far distances, at a speed of up to 45 miles per hour, the internal pressure to create the propulsion comes from an osmotic process.[1]
