A pair of soob lom, i.e. cylindrical bellows, which consists of a hollow cylinder with a small vent, usually a circular hole, located on the side, at the bottom, which is otherwise closed off, while the top is open. The cylinder is fitted with a long stick to which a round, disc-shaped sucker is attached, akin to a piston.

By pulling the stick up and driving it back down through the shaft, the air caught in between is compressed, but because of the outlet at the bottom, it escapes through the opening, emitting a blast of air.
