Abstract

A yo-yo with laser emission means mainly includes two side covers each defining a hollow space for accommodating a middle disc therein. The middle discs are provided at their outward-facing surfaces each with a seat for separately receiving a laser emission means and a light-emitting means therein, and a battery room for accommodating serially connected batteries. The laser emission means and the light-emitting means have terminals led to the batteries. When the yo-yo is manipulated by a player to rotate at a high speed, the terminals of the laser emission means and the light-emitting means contact with electrodes of the batteries due to centrifugal force and are energized by the batteries to emit laser beams and lights, respectively. The laser beams continuously project from an opening provided on the side cover and toward different directions and the lights illuminate the yo-yo, making the yo-yo particularly distinctive in the night or at a dark place.
