It is understandable that Mr. Carrow intended to write a bookthat would inspire creative thought in its young readers.Regrettably, what will probably be inspired is a mad dash to the local Radio Shack with Dad or Mom's credit card in hand.
This book is long on ideas and short on answers.
The definitions of technical terms and their integration into the book are good, but their relevance is questionable.
Some of the proposed "solutions" are not just inaccurate, they are un-workable as presented. The scarecrow mounted to the axle of a remote-control car comes to mind.
All in all a good book for an Aunt or Grandmother to buy for their precocious 10 year old, who will read the first six pages and then put it on the shelf to gather dust with the rest of the "good" books.
