I love browsing the internet looking for new and interesting toy related stuff. I happened to chance across this very different site which has some great ideas on how to make toys out of - yes, you are reading right - trash! It's called Toys from Trash. There are all sorts of toys you can make ranging from paper toys like flapping butterflies and fan tailed birds to more hi tech toys like a balloon pump or even a portable electric generator. I found quite a few of the ideas very do-able with parental supervision and help, of course. They range in levels of difficulty, so I advise parents and educators to choose the toys to make carefully according to the child's age and skill level. Most of the toys shown on this site illustrate to kids the basic principles of physics. Check it out at Toys from Trash.
