This Dinosaur Drop Roller Coaster Building Set from K'Nex is a fun way for kids to learn. Kids can grasp STEM (science, technology, engineering and maths) concepts as they create a kid powered roller coaster from 361 pieces. Build it and then ride it with the K'Nex Ride it! app! The app takes play to a whole new level as you can either ride your creation in 2d or in VR (viewer required).
