A miniature electrically powered thread reel and precision spooling mechanism fully and discretely hidden inside the cap of a working ink pen. Primarily intended for use by magicians during routines that require a super-thin thread be used for secretly controlling the motion of small objects. The device is completely self-contained and internally houses all necessary components required for normal and reliable functioning. The reel mechanism consists of a spool, spool-cap, motor, motor-housing, switch, battery, electrical contacts, and connective wiring. The main body of the pen is split into two primary sections and is retractable in length. This specialized body configuration is required because the cap contains the reel mechanism, and as a result is not hollow like an ordinary pen cap, so the body of the pen is segmented allowing the halves to slide together. Collapsing the body compensates for lack of space in the cap by shortening the overall pen length, and allows the cap to be put on and taken of without revealing the specialized nature of the device. An internal spring causes the hidden section to telescope out quickly as the cap is taken off, and this gives the appearance of a regular full-length pen being removed from a normal cap. The pen body has a secret compartment for holding an extra replacement thread-spool. The batteries and ink cartridge are standard size and can be replaced when needed. Other than the features described above the device looks and functions like a standard ink pen.
