      My son saw this book advertised in The Boys Life magazine. He put it on his Christmas and has been engrossed ever since. I found myself browsing and thinking about attempting some of the antics suggested.

    • Hours of entertainment
      Verified Purchase

      My 7-year old daughter has been wanting this book for ages, so when she finally received it in the mail she spent a solid week going through all the pages and testing out jokes, tricks and activities. The book is thick and packed with entertainment. THe product description states is for kids 8 and up, but my daughter is 7 and she and her 5-year old brother both have great fun with it. I would recommend this book to anyone with young children who can read by themselves. Also, shipping was prompt and problem-free.

    • Great Book
      Verified Purchase

      Seen the book previously, it brings back fond fun memories. It contains lots of things to do besides stare at the computer or watch videos. Get out there and play - no great funds required, just an imagination and humor. This is the second copy I bought! The first was a "retirement' gift to an old friend. You're never too old to have good clean fun.
