Review title: Outdated materials lists and bad science
Product review: I wish I hadn't bought this book. It was written in 1959 and, of course, uses 1959 household materials. When was the last time you had a glass baby bottle or even a glass soda bottle lying around? How about that screw top can of floor wax? This needs updating badly.One of the first experiments is titled, "Which is Heavier, Hot Air or Cold?" The explanation just concludes hot air weighs less without explaining that, with applied heat, some of the warmed air expanded out of the bottle. There's less air in the bottle to weigh!I can not recommend this book. If you use it as is, you will find yourself constantly searching for substitute materials. You will also be teaching incorrect or incomplete concepts.
