Watch the fish swim
This new mechanical aquarium model kit from UGEARS is an ingenious saltwater fishbowl with two tropical fish chasing each other around in a forest of macroalgae fronds hiding a seahorse.
Exquisite design: Once assembled, this super wooden mechanical model puzzle will adorn any office or home by displaying the beauty and mystery of saltwater aquariums.
Easy assembly and 6 hours of quality time: Everything you need to build our hobby kits for adults is in the box. You will experience the satisfaction of creating something beautiful with your own hands without using glue or special tools.
Innovative mechanism: To date, all UGEARS DIY kits for adults and building kits for kids have been propelled by rubber band motors, but the mechanical aquarium building kit is driven by a spring for longer action and greater longevity. As a result, the fish and algae rotate simultaneously and in parallel at different speeds and different directions, simulating the smooth, undulating rhythms of underwater plant and animal life.
Join our worldwide family: Thousands of people of different ages in 85 countries across 5 continents enjoy building UGEARS charming and unique brain teasers and making mechanical engineering gifts of our 3D wooden puzzle for adults and children.
