Dip into a fascinating underwater world with this whimsical wooden UGears Mechanical Aquarium!

Pop out the laser-cut pieces and begin the journey of assembling them to build an aquarium complete with tropical fish.

Once complete, watch as they chase each other around a fantastic forest of macroalgae fronds that hide a secretive seahorse!

To set things in motion, wind the knob on the base, the flip the switch from “stop” to “swim” mode and watch your aquarium come to life!

The fish look like they're really swimming as they move their heads and tails from side to side, powered by a spring-loaded mechanism!

You can stop your model at any time, or just let it go and enjoy the movements of the automaton fish and fronds for about 40 seconds.

Everything you need to complete your project is included in your kit. No glue or special tools required.
