Abstract: A selectively controlled displacement container is insertible in a standard toilet flush tank. The bottom of a container has a discharge-fill opening, and the top has an air inlet controlled by a selectively activated air inlet valve. Opening this valve adds the contents of the container to that of the surrounding tank. The valve can be restored to closed position by buoyancy forces on the following tank fill.

Abstract: A skewer for shish-ke-bob and the like comprises a cylindrically shaped handle having circumferential grooves and a concave recess near one end to provide a grip for a human hand. A shaft extends from one end of the handle. The shaft has a free pointed end and a small flange extending from the pointed end. A second shaft has one of its ends coiled about the first shaft for slidable movement with respect to the first shaft. The little flange prevents the second shaft from sliding off the first shaft. The flange can be threaded through the coil to detach the second shaft from the first shaft. A plate marker having apertures therethrough slides over both shafts. The plurality of apertures have distinctive markings. The plate is slidable along the shafts for pushing food off of the skewer shafts.
