Abstract: An apparatus and method of its use is provided for baiting a fishing line. A handle has a hole therethrough and a surface for gripping the handle. An elongate tube has a proximal end and a distal end and is fixedly engaged with the hole of the handle at the proximal end. The distal end of the tube has a terminal edge which may include a sharp edge for cutting through a bait. In use, a free end of the fishing line is threaded first through the tube, from the distal end to the proximal end, and then through the handle. The free end of the fishing line is then secured to the handle. A looped portion of the fishing line is then extended from the distal end of the tube and along the tube. The tube is then forced through the bait such that the distal end of the tube extends clear of the bait. The free end of the fishing line is then drawn out of both the tube and the handle.

Abstract: A base supports a vertical pivot arm, one end of which supports a pivotal rotation means for a rotation support housing with a plurality of radial connector sockets. One of several pendulum arms can be fitted into each of the radial connector sockets, the pendulum arms supporting a pendulous mass on each pendulum arm. One such pendulum arm is articulated into two portions, each portion with a plurality of additional pendulum arms attached thereto. The apparatus consequently demonstrates the physical principles of not just a simple pendulum, but those of a variety of compound pendulum configurations.
