Introducing the newest superheroes of New Bork City: Maker Girl and Professor Smarts! So what if they didn’t actually receive superpowers when that comet hit earth a few months back and created a bunch of other superheroes and supervillains? Maker Girl can make just about anything, and Professor Smarts is the sharpest kid on the block. They’re more than a match for villainous Mr. Anti-Freeze, who’s bent on ruining the town’s ice cream–by turning it all to slime! This fast-paced story delivers classic hero escapades with light-hearted twists, and readers can get in on the action by making their own super creations, from a toilet-paper-roll grappling hook to some delicious sorbet. Every colorful page bursts with kid-friendly art, hilarious characters, and the excitement of STEM.
