Negative Positive
Title: Parental Advisory
Review: I would advise parents thinking of giving this book to their teenage scientist to reconsider. Not because of the danger of catapults, Tesla coils, and air cannons--all that stuff is wonderful. But Gurstelle takes a four-page excursion near the beginning of the book into the wonders of penis-enlargement technology, in graphic detail. Completely out of place in this book, it makes no sense. It's just queer.
