Caption: Defying Gravity: Physicists Achieve "Impossible" Feat Of Rolling A Ball Vertically Down A Wall. Physicists at Canada’s University of Waterloo have achieved something extraordinary. They’ve made a ball roll vertically down a wall - defying gravity and upending conventional physics. Traditionally, vertical rolling is impossible without friction and torque. Even nature agrees: creatures like geckos cling, spiders crawl, but none roll down vertical surfaces. By re-examining textbook physics, researchers found the solution in softness and elasticity. A sphere as pliable as a gummy bear and a surface like a mousepad allowed for slow but steady rolling. The key, they discovered, lies in subtle deformation. The ball compresses slightly at the front edge and relaxes at the back, creating just enough torque for gravity-defying rolling. Prof Sushanta Mitra described the moment of discovery as 'stunning', challenging basic assumptions about motion. Though practical uses are still distant, the finding promises revolutionary possibilities in robotics and exploration.
