I have invented a method of using pop cans or any fluid containing container having selected characteristics that is fun and entertaining. This method comprises providing a container that is able to hold fluid and has a top, a bottom, and a vertical axis. The bottom comprises a first edge and a second edge, wherein the first edge is of greater length than the second, the first is nearer to the top than the second, and the vertical plane of the first edge encompasses the vertical plane of the second in at least a region. The first edge and second edge are able to contact a flat surface at the same time when the can is moved off-vertical. The container is tilted until both the first edge and the second edge contact a surface. The amount of fluid in the container is adjusted until the center of gravity of the partially-filled container is between the first edge and the second edge contacting the surface The method of the invention provides a container that is stable in a tilted position. The stabilized container may be rolled on its edges or left in a static position. This “trick” can provide enjoyment for people, particularly when the container is a pop can and others try to do the same thing with varied success. The container either falls back to a vertical position or falls over spilling the fluid contents.
