About this item

Big drops, wild loops, and plenty of “what if?” moments! Turn playtime into an amusement-park engineering adventure as curious builders design, test, and tinker with their own working roller coasters. Build dozens of models with sturdy modular pieces and flexible track. Experiment with taller hills, longer straightaways, loop-de-loops, car weight, and track slope, length, and direction. Explore gravity, force, motion, friction, and potential and kinetic energy through hands-on STEM challenges. A full-color manual provides illustrated, step-by-step building and experiment instructions.
