Check out this review from Myra Zarnowski at School Library Journal:

"This book explains the three major states of matter—solid, liquid, and gas—and shares how each one behaves. Once a state of matter is presented, Hays raises a question and suggests an incorrect but funny answer that children are likely to find amusing. Then they are presented with the correct response to set the record straight or asked to give an answer themselves. For example, readers are asked, “Why do gases get to go wherever they want? … Is it because it is almost bedtime, and their parents want to tire them out?” Then the following pages demonstrate that gas particles can move around a lot and fill up all the empty space around them because they are far away from each other. This format will keep children engaged. Infographics present examples of solids, liquids, and gases. The illustrations also provide images of many examples of matter. Readers are asked to find the different states of matter in the picture. This work informs while it entertains, ensuring that children are likely to read and remember the information. The colorful illustrations add both facts and humor. VERDICT Recommended for young children for its kid-friendly and accurate presentation of physics concepts."
