This concept would also generate educational opportunities for parents to teach the structural properties of triangles. 5) I’ve rated this as 5-stars because this kit, just as it is sold, is totally awesome, educational, and lots of fun for ALL of US kids! 6) Helpful Suggestions to the Manufacturer: #1) I would like to suggest that you sell add-on kits of various length rods, including some capable of fitting diagonally, like a triangle, both in a 2D square and a 3D cube box, placement of corner-to-corner of each. #2) The instructions state to place the etched surface of the connector sphere upward, but it is
