Objects used to improvise with. Note that most improv performances are done without props, and players mime any objects they might need (see Object Work and Space Object ).
Sometimes it may be practical to mime all objects needed in the scene, except for objects that might support an actor. So some troupes may have e.g. chairs on stage, and mime everthing else.
