The New Way Things Work
by David Macaulay
Recommended for ages 8+.
If you haven't 'discovered' this book yet - you're in for a treat! This is a wonderful book for budding engineers and architects! Paul (Jr) found this book in his school library and was so enthralled with it that we bought a copy for him to keep.
The book has awesome graphics and explains in great detail how things work. Examples include a gasoline engine, a refrigerator, a can opener, a clock, etc. This is a great book for people with curious minds, no matter what your age.
