Reciprocally rotatable complementary surface adhering portions (34 and 44) are provided integral to each of two manufactured objects (30 and 40) to be rotatably adhered, such as a bowl and a holding base. Being complementary in rotation, these adhering portions mobilize the forces of intermolecular attraction in any smooth, viscous, continuously flowable, non-curing liquid (50) compressed into a liquid film (52) across their interface and are rotatable upon each other while adhered. Media for rotatably adhering comprise a variety of liquids, among which are common household products such as honey, syrup, liquid soap, and many other such viscous liquids. Depending upon the viscosity of the liquid employed, portions so adhered at normal room temperatures will temporarily resist a tensile force in excess of 0.454 kg (1 lb) per 6.55 cm2 (1 inch2) equivalent to a pull of 13.62 kg (30 lbs) on a bowl having a base adhering radius of 7.93 cm (3.125 inches). Parallel movement inhibiting abutment means (56 and 56') are provided for inhibiting parallel movement of either manufactured object away from the other, while, at the same time, permitting their rotation upon each other while adhered. Thus separation by application of shear force or by simply sliding them apart is estopped, which means that some application of tensile force is required to effect separation whereby unadhering is controlled. Since unadhering can only be effected by application of some degree of tensile force, grappling means (62 and 64) are provided in certain embodiments to facilitate prying structures apart.
