Hydrodynamic Building Set
The heck with Lego or Erector Sets, here is the ultimate building game, a Hydrodynamic builiding set! You connect the girders and add the tanks, with a little help (but not total) from the instructions. Once it’s all connected, you turn on the power and watch the water flow!
Of course, if you have a school age child to buy for, this is an excellent gift that will make you the hero of both parents and child, but get one for yourself as well.
