what is the advantage of a drop kick
Drop kick Drop kicks are most importantly used as a method of restarting play and scoring points in rugby union and rugby league. Association football goalkeepers also often return the ball to play with drop kicks. The kick was once in wide use in both Australian rules football and gridiron football, but is today rarely seen in either sport.[citation needed]
Drop (liquid) 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.
