Oak Grove Gravity Hill Posted on July 18, 2006June 4, 2009 by Robin In Oak Groave there’s a hill that has reverse gravity. Balls roll up the hill, cars get pulled up the hill, apparently it’s quite something to see. Local residents admit it might be a visual illusion or that it might have something to do with a high concentration of ores in the soil and no scientific testing has ever been done on the phenomenon, but it certainly looks real.
