Reindeer Game Controller

A tool used by combining the parts and gripping each end of the rod. It is normally used seated, set on the desk in front of you, to enjoy shifting your center of gravity with a little of your weight on it, but it may also be lifted upward if that is not dangerous.

There is a hole in the center for inserting a micro:bit (microcontroller). If needed, it can be used as a play tool with sensors. Since the center of the ball is hollow, putting in a bell or the like so that it makes a sound when used is another idea.
