UGears Mechanical Aquarium
This 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!
This DIY aquarium model kit 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.
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.
