The Hydrodynamic Building Set looks a bit too complicated for me, in fact it gave me a small headache to look at, (it may be that I am “technically challenged”) but my daughter loves science and would probably be in heaven! Don’t be fooled, this isn’t a simple connect the dots contraption - there will be thinking involved.

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. If you’ve done it right, you’ll have an awesome construction everyone will marvel at (a little food coloring helps). Fail and you’re all wet - quite probably literally.
