this book was awesome! i'm 10 and i thought it was pretty cool! my brother, age 8, got it, and even my dad loved it! there r directions in the book for making this talking clock and when u press its head it says the time out loud. u can play around w/ the knob on the front and it makes it sound like alvin from alvin and the chipmunks, or turn it to the other side and it sounds like a demented giant!!! there is also a part at the end of the book where it tells u about robots, machiens, and computers which was really interesting. i think this is a real cool book for people ages 8-15, plus some grown-ups.
