Electromagnetic radiation is known to carry momentum, and this radiation pressure produces well-known effects from photoacoustics to astrophysics. Recent research has shown that this force need not be directly along the Poynting vector of the incoming light. This paper experimentally demonstrates a 'tractor beam' effect which can pull particles toward the source of laser light.
