It has a watertight disengageable closure between the ends, usually formed either as a cap or by unscrewing two parts of the tube and one or more intrusive portions of its wall extending into the inner space to promote turbulence when the tube is partly filled with clothes and water and then shaken. Larger sizes may be supported on two legs (or hung from a support) to facilitate shaking, and drain plates and water-removal ports can be provided.
