<P> A simple way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter . The surface tension of the liquid causes the liquid to hang from the tube , forming a pendant . When the drop exceeds a certain size it is no longer stable and detaches itself . The falling liquid is also a drop held together by surface tension . </P>
