Seemingly, we invert the gravitational law by making liquid flow uphill at the Physikshow of the University of Bonn! The clue is that the liquid is a salt (coppersulfate) and the duct has a magnetic field applied to it, and a current flowing from its one side to the other. Both the current and the magnetic field are orthogonal to each other and to the direction of movement of the liquid! http://www.physikshow.uni-bonn.de/
