An area object partially immersed in a liquid was buoyed upward Tuesday by a force equal to the weight of the liquid displaced by that object, witnesses at the scene reported. According to sources, opposing forces acted against gravity during the displacement. In addition, though the object reportedly seemed lighter, it only appeared weightless due to the fact that the density of the liquid surrounding it was only slightly greater than that of the object. As of press time, the object is still maintaining positive buoyancy.
