Surface Tension Man

Climbing walls just got easier with surface tension and some brains. A palm-sized device was made by researchers at Cornell which uses the combined surface tension of a series of minute water droplets to create a strong adhesive force. Using an electrical field to pump the water through the holes, he can also reverse the process, allowing the plate to become unstuck on demand simply by changing the electric field. So climbing walls just got easier and you may not need to be bitten by a radioactive spider.
