Abstract: A device and system for use with a plurality of the same in constructing objects from empty beverage cans which device includes a disk adapted to be received in the cavity between the recessed end members of two abutting axially aligned beverage cans to maintain the alignment thereof. A threaded member projects from one side of the disk and a spindle projects from the other side. The outer end of the spindle is provided with a threaded bore adapted to receive the threaded member from another such device. The spindle passes down through an opening in the top end of the can, while the threaded member of another device passes up through an opening in the bottom of the can. The threaded member threads into the spindle disposed therein to "sandwich" the can between two disks and provide a threaded member and spindle with which to continue the process. In this manner, a series of cans with the devices disposed therein may then be connected, either directly or through a shelf member.
