These animated dvds are educational without being at all boring. The fundamental principles of physics are taught in a way that even very little children find absorbing and understandable. My 3 and 5 year old boys can be monkeying around and being very hyper one minute, and then sit awestruck and very engrossed watching one of these DVD's.
My five year old really does absorb the scientific principles The Way Things Work aims to teach - I know this because he will apply some of them in his play with lego, traintrack building, and so on and also he will astound me by relaying a principle he has learnt in our casual conversations.
The DVD's are superbly animated, and not at all americanized or patronizing, I would say this double DVD set has appeal for all ages - even my wife and I like watching them. We also have the book, which is a really useful reference book for schooled or home-educated kids alike, and indeed for the whole family!
