You have found the non-commercial site for people who like to roll up their sleeves and make science toys and projects. You won’t find slick, well-designed web pages here–more like the digital equivalent of a messy workshop. If you poke around, though, you’ll find good stuff. Science toy maker is a resource for inspired kids, parents, teachers, teenagers, home schoolers, science fair participants and citizen scientists everywhere. There are a few hard-to-find items for sale here and here, but all proceeds go directly to an education non-profit, the Physics Factory.
