"REINVENTING THE TATTOO" Trivia Question #13

_________ _______ is the movement of fluid in the spaces between the needles.  

Answer:  CAPILLARY ACTION - Under ideal circumstances, the spacing between the needle shafts will contribute to the ink flow from the tube tip toward the points.  When there is enough space between the points, pigment will flow between them, covering the whole surface of each point before the needles are driven into the skin.  Better capillary action equals better pigment saturation in the tattoo.
