UGears Mechanical Model - Aquarium

The Mechanical Aquarium from Ugears is an ingenious saltwater fishbowl, with two pet tropical fish chasing each other around a forest of macroalgae fronds, inside of which hides another small inhabitant of the marine environment—a seahorse! The beauty, variety and intrigue of saltwater fish-keeping makes it one of the world's most popular hobbies. Perhaps you are a snorkeling or diving enthusiast, and would like to be reminded of underwater adventures when you've dived a colorful reef or explored a kelp forest. Building Ugears' charming and unique wooden models, brain teasers and 3D puzzles has become a popular hobby for thousands of people in 85 countries across five continents. Now you can combine these hobbies in a single model.

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.
