Almost New - appears new but is actually secondhand.
Very Good - only minor imperfections such as minor scuffs to edge or cover or a price written in pencil or shop sticker.
Standard Secondhand - Clearly been read before, but not too bad. We do not recommend these for gifting. Spines usually creased. Could also include creases or folds to cover, some writing such as in the cover or elsewhere, underlining or highlighting, but might not do. Possibly some stains or marks. Similar in general to books in any secondhand shop or charity shop.
Poor Condition - Usually this will have a specific problem such as writing inside, water damage, missing dust jacket, heavy staining, large creases or cuts. These are readable copies but not nice ones. On other websites this condition is called 'Acceptable' or 'Fair' , but we want to be more honest.
More than 200 fascinating science puzzles perfect for astounding friends, impressing party guests, and annoying relatives
A book for the curious, this engaging read takes a slightly different look at puzzle questions--every one is based exclusively on real world science. Using scientific principles, it teaches how the moon causes tides, how one can walk on a tightrope, why a golf ball has dimples, whether you can cool a whole room by leaving the refrigerator door open, and what makes glue stick. The answers to these and many more puzzles, queries, and curios are found inside the pages of this volume of educational fun.
