Query: Fun and Interesting!

Have you ever wondered why pigs are roasted with an apple in their mouths? Or perhaps wondered why covered bridges are covered? Maybe you've always wanted to know the answer as to why we wave Polorids in the air after they come out of the camera? If you have, then this is the book for you! Even after so many other books in the Imponderables series, this book is still interesting. However, I recomend flipping through it, reading only the questions that interest you. If you read it cover to cover, it won't be as enjoyable. It also features the popular "Frustables" column, and an all new section with letters from readers. Overall, it's a fun and entertaining read.
