In today's era of widespread automation, we rarely have the opportunity to personally "drive" a complex machine and observe how its internal mechanisms transform simple inputs into complex outputs. This is precisely the unique charm of the "Mechanical Fish" exhibit. It completely exposes the transmission mechanism, usually encased in a shell, inviting visitors to become the "prime mover" of the entire system. When you turn the handwheel, you provide more than just power; you initiate an exploration of "motion transformation." You will see how a simple circular motion is altered in speed and direction by gears, how it is transmitted to a distance by a chain, and how it is ultimately "translated" by the connecting rods into the lifelike left-right swaying of a fish's tail. This process is full of mechanical certainty and geometric beauty; every meshing and every transmission is clearly visible, transforming the abstract "mechanical principles" into a tangible, controllable narrative.
