Set contains approximately 300 pieces.

Build a model of a manufacturing plant with working tanks, pipes, valves and pump with this unique construction toy. A color instruction book provides building instructions and several examples of different structures you can build with the set.

With the HYDRODYNAMIC Building Set you can build a model of an ice cream factory, a water treatment plant, a distillation plant and many other industrial structures.

Discover how a siphon works. Balance the flow through the plant by adjusting the valves. The user learns the basic principles of fluid dynamics while constructing and playing with this toy.

This set comes with a large tray and footing in which you build the structure. The tray measures approximately 10 inches by 16 inches by 3 inches deep. The tray and the footing are both white. The footing has a grid of 12 holes for columns (4 x 3 configuration). Build the structure using the footing in the tray for the base, place the submersible pump in the tray, add water until you completely cover the inlet on the pump, and then enjoy reconfiguring the pipes, opening and closing valves and watching the action! When you take the set down, all the parts pack into the tray, the plastic lid snaps on and it can be safely stored away for future use.

This building set includes an electric pump, siphon tank, large square tank, small and large round and cone bottom tanks, float valve, tilt scale, ball flow meter, water wheel, spray head, and assorted valves, pipe holders and pipe. The pieces are interchangeable with all other Girder and Panel and Bridge and Turnpike Building Sets and are HO scale. This set is great for doing middle and high school level science fair projects.
