Using a small battery, a magnetic reed switch, and a miniature pager motor, this device will fit concealed inside a fine-point Sharpie pen. When a magnet is drawn near, the contacts on the reed switch close, making the Sharpie dance and vibrate on a table. I call this device the Telekinetic Pen.

The entire device can be built in an hour or two, with only a couple of soldered connections and a little work with hand tools. You can even “prove” it’s a real pen by writing with it.

The Telekinetic Pen is a real attention-getter, and as far as the requisite magician’s patter and routines, your imagination is the limit.
