Read the fun story of two young engineers, Ty and Karlie Omega, and build simple models of the amusement park rides they encounter on their family outing. Along their roundabout journey, the kids build, fix, and enjoy various amusement park rides. As you follow the story, you can build and experiment with models of the 20 structures and machines in the story. The kids start out by testing ten different configurations of roller coaster tracks. They try out flat tracks, slopes, humps, and curves. They proceed through the park to build and fix a Ferris wheel, merry-go-round, pirate ship pendulum, bumper car, free-fall tower, log flume ride, and more. Along the way, they learn simple physics and engineering lessons.
