Finally, a concise, interesting, and clearly written book which explains electricity to readers who don’t have a technical background. All examples and situations discussed are related to the home. This book is intended for all persons, from curious young teens to adults who want to have a better understanding of this important power source. Irwin Math's book will give the ordinary person without a technical background a general idea of what electricity is, how it is produced, how we use and measure it, as well as the dangers involved with its misuse. A previous technical understanding of electricity is absolutely not necessary, and the book does not contain any complicated mathematics. Only one simple easy-to-understand formula is provided -- no more!!  The information given will also allow the lay person to begin to understand and even troubleshoot faulty devices, make simple repairs (often saving money in the process) and approach electricity with the respect it deserves. By carefully reading the chapters one will not only attain a good basic knowledge of electricity but be able to talk to an electrician, when necessary, knowing and understanding pretty much what he or she is explaining.

Long lasting and fun
This toy has lasted longer than other octopus toys I've bought in the past. Even if a leg or two is ripped off, it still holds on.

Awesome product, but NOT sturdy
My dog LOVED this product, but unfortunately the head came off in less than a week.

Glad this toy is back
Large soft dog toy. I have been trying to buy this item for years. It apparently was discontinued, but it finally has been replaced with an even better, more durable product. I have two large chocolate labs and they have yet to gut it. It is reasonable durable, but I suppose a determined dog could eventually rip into it. I will definitely again. Large grunting noise maker in the body, and small squeakers in the arms.

Fantastic octopus
Color: Blue
This toy is everything for my 15 lb schnauzer. Tons of crinkles in each of 8 legs and squeezes easily at head. He has over 75 toys and is one of his top 5 toys now. Great size not too big. Dog see blue and yellow so a plus. Rest of colors to them are shades of black, greys and to white.

Cute and fun!

This was exactly as described! The head has a squeaky and the legs crinkle. I have a small dog who does not destroy her toys so I think this will last a long time. So far—she loves it!!
