Chris sprained his ankle, and engineers Zoe, Gabrielle, and Rosita want to bring him his lunch in a new way, using a rope and pulley. But the rope slips off the lunch bag. This is a problem! They wonder if there�s something they can put the lunch bag in and tie the rope to. What if they put the lunch bag in a basket and tie the rope to the basket handle? Let�s try! It works. Zoe, Gabrielle, and Rosita didn�t give up and found a new way to get Chris his lunch.
