Abstract: A method of exercise includes partially filling (not more than 70% full) a symmetrical hollow body of an exercise device with water, grasping a pair of opposed handles attached to the hollow body, positioning the device at a height and orientation for a first set of motions, and rapidly oscillating the device at a frequency (?2 HZ) to transform the water from a static state into a dynamic state in which the center of mass oscillates and hydrodynamic forces arise. Optionally, an additive such as viscosity enhancer or beads for audible effect may be introduced in the water.

Abstract: A tilt-able flat table, mounted on cams in a frame, retrieves rows of containers from a stage and deposits them in a box. The table is mounted on a horizontal tilt axle which is borne between two parallel cams. The tilt angle determines the path of the containers into the box. The cams rotate about a cam axis which determines the position of the table relative to the frame. Container top bands engage the containers on the table and move them in the forward-rearward direction on the table. The frame is movable relative to the box.
