Book excerpt: Who knew science could be so smelly??? This innovative book is a complete exploration of the olfactory system, with a side of gross-out hilarity. First, it tackles the basics, from why things stink to how our sense of smell works (hint: it has to do with the six million scent receptors way up inside our noses). Then, it moves on to some specifics such as the link between smells and memories, some of the stinkiest stinks on Earth, the chemicals smells are made of and more! The eww! on every page is sure to hold every young scientist’s attention!
