Abstract
A submergible stool includes a body having a top, a bottom spaced from the top, and a sidewall extending between the top and the bottom and defining an enclosed interior cavity extending between the top, the bottom, and the sidewall. A first aperture is formed in the sidewall proximate the bottom and extends from the enclosed interior cavity to an exterior of the stool. A second aperture is formed in the sidewall proximate the top and extends from the enclosed interior cavity to an exterior of the stool. The apertures are positioned such that when the stool is placed in a body of water, water will flow into the interior cavity through the first aperture, air will be forced out of the second aperture, and the stool will sink to a bottom of the body of water in an upright position.
