The performer presents a three-legged table. S/he places his/her hand upon it and waves the magic wand at it and mumbles proper threats or encouragement. When the spell "takes effect", the performer lifts the table into the air and waves it around, following the wand, using only the hand which is laid flat upon the table top.
The top of the table is covered with some plush material. In the center of the table is a nail; the performer wears a ring which is notched. The performer locates the nail and jams the notch against it; once this is done the table can be manipulated as desired.
The spell-casting need last only as long as the performer needs to locate the nail. For best effect, follow the wand very strictly.
