ABSTRACT:
A water skipping article for use by a user in launching the article in a substantially horizontal trajectory and with a specified rotation spin. The article includes a three-dimensional body constructed of a biodegradable material and having a smooth and continuous exterior surface with a substantially circular and smooth edged outer perimeter. The body further includes a side profile defined by upper and lower elliptically extending faces and which converge into the smooth profile of the circular outer perimeter. A hollowed, substantially elliptical and interior cavity is defined in substantially centric and suspended fashion within the body. Upon launching of the water skipping article by the user, the configuration of the interior cavity causes centrifugal forces to be applied in a direction towards the solid outer perimeter of the article and to thereby increase individual incidences of the article contacting the water surface in a skipping fashion.
