Chattanooga Sludge is all about inventions and scientific experiments! When a bad odor starts forming in a sludge filled river, the professionals must quickly think of a way to stop the smell and get the poisonous chemicals away from harming the people. Luckily, after much thinking and testing, a way to get the chemicals out is found! This book can be a little confusing with all of the scientific terms in it, so make sure to pay good attention! If there is a problem, after a little thinking and testing, an answer can be found. Don't give up on something if it doesn't work the way you wanted it to the first time. ( )
