lexa Coelho is a curious teenager who asks a lot of chemistry questions. He lives in Los Gatos, California.
"Many of Coelho's questions are things that other adolescents (and adults) may have wondered, and here they are answered by a knowledgeable scientist who gives readers all the tools they may need to understand the complex chemistry of the everyday world." -- Booklist "Just the book to inspire the budding chemist, or simply entertain, while teaching, the rest of us."-- The Pioneer Woman
