Friday Fun Gadget - Hydrodynamic Building Set
![]()
A full on geeky water playground - I’d even take a few hours of the weekend to goof with this thing. The girders connect,to build the various tanks. Your entire model gets built up from the bottom of the carrying case, which acts as the water reservoir and also has a special footing to be the structure’s foundation. Level by level, you build your support frame and add your tanks. Then connect all the tubes, add in the valves, and turn on the electric pump. 300 Pieces!
Whats more fun that water and electricity together eh?
