Forget children 8 and over, take my money now. I can see myself sitting and playing with this kit for hours and I am well over eight years old. I kind of reminds me a lot of my dad erector set he had when I was a kid. The pieces just have that feeling to me. This looks like it would be a great way to get anyone involved in science. It also could be a great introduction to the growing world of solar power. Thanks for sharing. Nice hunt!
