How The Body Works. (Projects for kids)

Anyone seen these little cool 'projects' about ?

I bought my nephew two little projects last week at Milton Keynes. You get a box with all these little 'ingredients' in. I bought him 2. One 'Make An Eyeball And See How It Works' and another 'Make Your Own Brain And See How It Works'. They are pretty damn cool for children, as it comes with a little book of facts on how these parts of the body work .. you create them and paint / colour them. VERY beneficial imo. Helped my nephew 'build' them and told him all the facts which are quite fascinating for young children !
