Lab Equipment  Directions
  1.  Chrome laser pen
  2. Small lab stand and 3 finger clamp
  3. Black sheet of reflective plastic
  1.  Arrange the set up so that when the vertical laser beam hits the plastic it is reflected onto the wall or ceiling.
  2. Rotate the laser in the finger clamp until the beam is horizontal. Notice that the projected reflection disappears.
  3. Adjusting the angle of the reflected beam will fine tune the effect.
