Jizerian anti-gravitypoint

According to some observes, this point is agravitation alanomaly that causes an object (e.g. a ball) to roll up the hill without help. The Iserian anti-gravity point is also described as an ordinary optical illusion influenced by the terrain. The point is characterized by a special rock sculpture, which is very easy to reach. We Gould recommend physics enthusiasts to make an appropriate test here.
