Developed by researchers at the University of Canterbury in New Zealand, this bot can wind its way across any glass, metal or cloth terrain, without even touching its pods to the surface. The secret lies in Bernoulli's Principle, which states that as the speed of a fluid increases, its pressure decreases.
