Researchers have developed a tape so strong that the amount needed to cover your palms could let you stick to the ceiling.
A combination of capillary force and Van der Waals interaction supply the stickiness.
However, it turns out the scientists are spoilsports:
“We have also considered producing a large amount of gecko tape, sufficient amounts to enable a student to hang out of a window of a tall building,” Professor Geim said. “However, it would cost too much money, and would not benefit us scientifically, so we have limited our demonstration to the Spiderman toy.”
