Van der Waals force

A type of technology that allows heavy objects to cling to walls. 10 years prior to the events in Metal Gear Solid 4 Otacon stumbled upon some research that reportedly was able to suspend and object weighting 100 grams using a 5 millimetre square piece of tape. He believes this technology has evolved into what Vamp, Metal Gear Gekkoand the FROGS are using today. Snake is relieved to hear that Vamp does not actually have super natural powers.
