I can't say enough great things about K'nex. They are an awesome toy, but they are also a great tool to help your child learn and grow. The pieces click together very strongly and don't fall apart. [...] They can be used for creative play and unlock imaginations and help learn how things work.

I played a lot with K’NEX as a kid, and eventually went to college for civil engineering. They functioned as a knuckle-destroying outlet for my creativity. [...] We need kids with an eye for infrastructure if we are going to build a world we want to live in.
