Surprised that such a site is present with so many so many projects & toys, that too made from nothing.
Thanks to the author as well as heath who gave the link.
Its not just that there are so many projects, but that we can teach our child - even broken toys and waste material can be utilized in so many ways to have something useful & fun. Instead of throwing into dustbin, we can use them to create for our child or give to underprivilidged, apart from learning & teaching so much from the science projects & toy making process & books.
One cannot imagine how much time and effort must have gone to create such a huge site with huge variety of things.
