The Painleve-Gullstrand coordinates provide a convenient framework for\npresenting the Schwarzschild geometry because of their flat constant-time\nhypersurfaces, and the fact that they are free of coordinate singularities\noutside r=0. Generalizations of Painleve-Gullstrand coordinates suitable for\nthe Kerr geometry have been presented by Doran and Natario. These coordinate\nsystems feature a time coordinate identical to the proper time of\nzero-angular-momentum observers that are dropped from infinity. Here, the\nmethods of Doran and Natario are extended to the five-dimensional rotating\nblack hole found by Myers and Perry. The result is a new formulation of the\nMyers-Perry metric. The properties and physical significance of these new\ncoordinates are discussed.\n
