Abstract
A noise-maker includes an enclosed membrane having an inlet and an outlet that is filled with porous material. The noise-maker is in an inflated state when the porous material is saturated with air and a compressed state when the air is forced out of the porous material. When pressure is applied to the noise-maker, the air inside the membrane is forced through the outlet and the noise-maker reaches the compressed state. When the pressure is released, the noise-maker changes from the compressed state to the inflated state as air flows through the inlet.
