This is a solid, funny picture book that does exactly what it sets out to do: make kids laugh while gently skewering science fair culture. Barnett and Santat are a strong team—the story moves fast, the illustrations pop, and the premise is absurd enough to delight without tipping into chaos that stresses kids out.
It's not going to change anyone's life or teach deep STEM concepts, but it normalizes failure in a way that's genuinely helpful for kids who put pressure on themselves. The girl protagonist is ambitious and creative, and even when her robot goes haywire, the tone stays light and fun.
At 15 years old (published 2010), it still holds up well—the humor is timeless, and Santat's art style hasn't aged. A great pick for read-aloud time or independent readers who like their stories with a side of mayhem.
