I value Curtis Kam’s magic and his thinking. My newest aquisition is his take on the infamous three-ball-trick.
Okay—you’ll have to get your hands on the “gimmick” Mr Kam suggests, but that should be in the range of everybody.
Props cost: about $30. Instructions excellent, so you have that new trick in your arsenal. Especially good for parlour/small stage performances. What else could you ask for?
