Query: A simple table-top demonstration of radiation pressure on a macroscopic
  object   We report a simple demonstration of radiation pressure on a table-top
experiment. Utilizing dynamic force microscopy in ambient environment, the
resonant motion of a cm-sized cantilever driven by an amplitude-modulated diode
laser is directly observed. Our versatile setup involves a host of exciting
techniques that are relevant in precision force measurements and represents an
ideal experiment in the undergraduate laboratory.
