Painters and photographers have long exploited this effect, for example, in imaging scenery distorted by ripples on a lake. Here, we use this phenomenon to visualize micrometric surface waves generated as a millimetric droplet bounces on the surface of a vibrating fluid bath. This system, discovered a decade ago (Couder et al. 2005 ), is of current interest as a hydrodynamic quantum analog; specifically, the walking droplets exhibit several features reminiscent of quantum particles (Bush,&nbsp;<em>ARFM<\/em>, 2015). We present a simple and inexpensive experimental device that allows one to see many striking pilot-wave phenomena. It is our hope that this will be of interest as a high school physics classroom demonstration. <br><br><\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/thales.mit.edu\/bush\/wp-content\/uploads\/2021\/04\/FlowViz3.png\" alt=\"\" class=\"wp-image-6110\" width=\"537\" height=\"501\"\/><figcaption>Visualizations of pilot-wave hydrodynamics.<\/figcaption><\/figure>\n\n\n\n<p class=\"tw-text-wide has-small-font-size\">See paper here: &nbsp;Harris, D.M., Quintela, J., Prost, V., Brun, P.-T. and Bush, J.W.M.
