"With the School Invention Fair coming up, Sam is determined to invent the best invention. First, he builds a robot that'll clean the toilet (but it refuses). He tries a fart fan (but that just creates a mess at lunch). Will Sam come to the fair empty-handed, or will he create something great and win a prize?"--Publisher's statement on Amazon.com.
