June stories at the FCP site: (1) A circus act of balancing long rods is a dramatic example of center of mass. (2) Chladni singing, in which the voice shapes patterns of salt on a plate. (3) Footsteps momentarily dry out wet beach sand. (4) Pushing a drinking glass into sand flluidizes the sand. (5) Pub trick: inflating a long sandwich bag with one breath.
