We report on the strange physical motion of balls rolled inside a cylinder, which at a glance seems to contradict physical laws. Based on this motion, we develop a new type of juggling in which several balls are manipulated in a cylinder to draw a variety of spatio-temporal patterns. In the presentation, we will demonstrate some manipulation.
