Engino Mechanical Science: Screws
Engino Mechanical Science: Screws.  This Engino set introduces young engineers and physicists to how worm gears are used to greatly lower rotational speed, and how screws can convert circular to linear motion while greatly increasing force.  Build 5 working models including a screw press, a folding lift platform, 2 cranes, and a vice.  A  40 page activity book is uncluded with innovative experiments and detailed explanations of various technical and scientific principles and how they are applied.    The Engino Toy System is perhaps the most advanced and versatile three dimensional construction toy in the market today.  It offers both children and adults unique opportunities for design and creation.  The system is comprised of multi-faceted rods and connectors that share some unique geometrical features that allow connectivity on up to 6 sides simultaneously.  In essence, the patent pending design transforms rods into connectors and allows dense or open construction.  This allows engineers to build simple or complex models quickly with a smaller number of different components.
