  • Patent number: 5641140
    Abstract: 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 cm.sup.2 (1 inch.sup.2) 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).
