Right angles are all wrong for tree frog adhesion
...gradual process, with adhesive forces weakening at angles above 90. Thus frogs maintain a grip by keeping the angle of their toes with respect to a surface at a low value, and detach when this angle increases beyond 90. By examining the behaviour of the frogs researchers were able to correlate this observat...Press conferences at the year's largest physics meeting
