“Build it! and Ride it! with the K’NEX Thrill Rides Dinosaur Drop Roller Coaster with the K’NEX Ride It! app. Experience K’NEX Thrill Rides in a whole new way with this dinosaur themed coaster perfect for boys or girls ages 7 and older. Build the Dinosaur Drop toy roller coaster with the included 361 K’NEX parts and pieces including coaster track, roller coaster car, and themed graphics! The rods and connectors click together to create a 3D configuration and a coaster that stands over 1.5 feet tall. The Dinosaur Drop Roller Coaster has a kid powered slam launcher which sends the coaster car rocketing up the track. In a new twist to K’NEX Thrill Rides, upon completion of building the coaster, children can download the free K’NEX: Ride It! app to take their play to a brand-new level. Once downloaded, children can ride the Dinosaur Drop Roller Coaster in 2D or in VR, if a virtual reality viewer is accessible to them. Or, take building into the digital world! Rebuild the Dinosaur Drop in the app or create any coaster you can imagine. Once done building in the app, kids can then ride what they just built! The K’NEX: Ride it! app perfectly marries a hands-on building experience with a mobile app. This set does not come with a VR viewer.
