I thoroughly agree with the other 1-star review. My son, who is nine, enjoys science and was excited to get this book at a local used book store. As with most books of this nature, I handed it off to him to read and enjoy. For days, he told me how excited he was to try one particular experiment in the book where we could "make a diamond." I thought it sounded a little unbelievable, but of course I read through it with curiosity and an open mind, thinking it was just an exaggeration of the actual outcome and never imagining that it was 100% fake...because why would anyone ever do that and why would a publisher allow it?Yep, a fake experiment in the middle of a science experiment book for children with nothing but a warning in the (rarely read) introduction. Teaching children to think critically is one thing, but teaching them to be snarky, distrustful cynics is another. This felt like a cruel joke. My son felt tricked and betrayed, when he should have felt he could trust an adult. I can see, perhaps, having such an experiment in a book for teens, but these types of "life lessons" should be done gently and carefully with younger kids. It makes me wonder how much time the author has actually spent with kids.The other experiments do look interesting and perhaps I could give it a couple stars if I wasn't a mother. But anyone who is a mom understands how much we HATE to see our children hurt for not good reason! He was almost in tears and I had a very hard time explaining to him why anyone would do such a thing. What a dumb move for both author and publisher and I hope they reprint with this obvious gaff removed!
