Sid has a big, big, big problem! He's trying to grab a cereal box located way up high on the kitchen shelf, but he just can't reach it. He tries using a stool, but he still can't grab it. He wants to know, how is he ever going to grab that cereal box??? At school, Sid and his friends encounter another problem. They need to get a ball down that got stuck in a tree. Susie has an idea. If they have a problem, it's time to "engineer a solution." The kids work as a team, brainstorm some ideas, draw pictures of their ideas, and then try building their ideas. And to make the day even more exciting, Dad visits school and volunteers to help the kids build a special "grabber" to get the ball down from the tree!
