The magician tells the audience that he will now demonstrate a revolutionary new method of teaching golf. From a black box held in his hand he removes a "golf cube" which is "for beginning golfers". "The task is easy - all you have to do is get the cube into the hole" (the empty black box). "You need to practice it until you get a hole in one!" He places the "golf cube" into the black box where it immediately turns into a golf ball! "This is the advanced level. To play golf you need a green!" A green cube appears from the black box. The final surprise: Everything can be examined immediately by the audience! With instructional DVD (English).
