1. An aerodynamic disc, comprising:

  • a disc having a convex top, concave bottom and a depending peripheral rim extending downward a particular height, the concave bottom having a threaded mounting boss, the boss extending downward less than the height of the rim;

    a flexible protrusion threadedly attachable to the boss so that when tightened, the protrusion is fixed to the boss in a non-rotatable configuration;

    the protrusion extending significantly below the height of the rim so that when the disc comes to rest on the ground, it rests at an angle and is supported by the protrusion and a portion of the rim;

    the protrusion being substantially flexible so that if the device is stepped upon by a user, the protrusion bends significantly under such force and will return to its original configuration upon the release of such force.
