Cheerios Force (IMAGE) Brown University Caption In a finding that could be useful in designing small aquatic robots, researchers have measured the forces that cause small objects to cluster together on the surface of a liquid -- a phenomenon known as the "Cheerios effect." The researchers used a custom built apparatus to measure the forces using magnetism.
