Water slider Giuseppe Pucci, Ian Ho and Daniel M. Harris
Photograph of a disk resting on the surface of water by virtue of the equilibrium between its weight, surface tension, and hydrostatic forces. The disk is embedded with a small permanent magnet, which allows to guide the disk on the liquid surface by means of an external magnetic field, and to study the friction experienced by the disk. The disk is coated with a commercial super-hydrophobic spray coating and has radius R = 8 mm.
