Gripping question."Caught on Tape: Gecko-inspired adhesive is superstrong" (SN: 6/7/03, p. 356) reports that, wearing a gecko-inspired glove, "a person could dangle dangle Nursing A popular term for the first movement a Pt is allowed, either after surgery under general anesthesia, or 'under local', where the recuperee allows his/her feet to dangle over the side of the bed from the ceiling."

Despite folklore to the contrary, their bite is not poisonous. peels them off the surface, changing the angle at which the hairs meet the surface. The same would go for gecko tape Gecko Tape (Directional adhesion) is a new material still in the development stages. Directional adhesion refers to the ability of an adhesive material to grip a load in one direction, and its ability to release its grip when the direction is reversed. and thus for gecko gloves. A person wearing gecko gloves would have to learn to peel his or her hand from the surface.--S. MCDONAGH |
