Not only is this DIY aquarium model kit, with its original theme and design, a fine addition to the Ugears catalogue, but it also features a unique mechanical action. The fish and algae rotate simultaneously and in parallel, at different speeds and in different directions, simulating the smooth, undulating rhythms of underwater plant and animal life. The elegant fish look like they are really swimming as they move their heads and tails side-to-side. The Mechanical Aquarium model is unique in that while many Ugears models are propelled by rubber band motors, the Aquarium is driven by a spring, for longer action and greater longevity. At Ugears we pride ourselves on innovating, and on listening to our loyal customers, many of whom have been asking for models with spring-loaded mechanisms. We are proud to bring you this spring-action aquarium—a first in our growing catalogue of Ugears models!
To set the model in motion, wind the knob under the aquarium with about 25 half-turns, flip the switch from "STOP" to "SWIM" mode, then watch as your Mechanical Aquarium comes to life! The mechanism contains an internal pendulum to regulate and smooth the movement. We have designed this model to be the very definition of operational simplicity for users: one switch, two modes: on and off. You can stop the model at any time, or just let it go and enjoy the movements of the automaton fish and fronds for about 40 seconds.
