Engino for ages 6 and up.Engino - INVENTOR 30, Multi Models - brings complex designs into simple focus with clear, 3-D rendered, printed instruction manuals.Build 30 assemblies from the manual including a Drag Racer, T-Rex, Crane, Draw Bridge and much more.Or add some imagination and make your own creation.The Engino Building System was invented by Costas Sisamos, a former teacher and engineer for the purpose of helping students build technological models creatively and easily to experiment and learn about science and technology in a way that includes all the benefits of play.Research grants from local and E.U.sources helped transition the three year research project into an innovative product.Since then Engino has developed more snap-fit components such as gears, pulleys, motots, and solar panels.The major advantage of the Engino system is that it's design flexibility enables children to build simple or complex models quickly using a small number of components.
