From The New York Times: “The set designers and the special effects team tried out several different materials for the stage floor. Some, like dirt, were not hygienic; others, like cork, disintegrated in the rain. They settled on a synthetic rubber used in playgrounds. It cushions the actors and allows them to slip and slide. Installed loosely, it resembles gravel. Underneath are wire mesh, sluice matting and subway grating, which help the rain flow into a drain pan.” |
