Renee B. - reviewed Mistakes that Worked: 40 Familiar Inventions and How They Came to Be on
My 14 year old son absolutely loves this book. We have had it for a couple years now and it still gets pulled out and looked over regularly. Periodically an item will come up in conversation and our son will say "oh that's around because of a mistake" and give us the history of the item, can't ask for better learning then that.
