Description Jabari is inventing a machine that will fly all the way across the yard! But making it go from CRASH to WHOOSH will take grit, patience, and maybe even a little help from his sister. Jabari is making a flying machine in his backyard! “It'll be easy. I don't need any help," he declares. But it doesn't work! Jabari is frustrated. Good thing Dad is there for a pep talk and his little sister, Nika, is there to assist, fairy wings and all. With the endearing father-child dynamic of Jabari Jumps and engaging mixed-media illustrations, Gaia Cornwall's tale shows that through perseverance and flexibility, an inventive thought can become a brilliant reality.
