Abstract: There is disclosed a method for effecting the continuous movement of a fibrous flexible sheet material body which includes the steps of providing an environment which includes a liquid capable of vaporization, providing a membrane permeable to the liquid and positioned relative to the liquid such that vapors emanating from the liquid make contact with and permeate the membrane, and providing a fibrous flexible sheet material body freely positioned on the surface of the membrane and above the liquid such that vapors caused by vaporization of the liquid pass through the permeable membrane and coact with the fibrous material to cause a twisting and moving motion of the body which remains continuous with the provision of vapors permeating through the membrane. There is also disclosed a game device embodying the subject method disclosed herein.
