Thames & Kosmos Roller Coaster Engineering Kit | Build, Experiment & Explore Physics & Motion

Turn science into park-yard excitement

The Thames & Kosmos Roller Coaster Engineering kit makes physics feel tangible. Build dozens of working roller coaster models using a sturdy plastic building system, then attach flexible track to test your ideas. The modular design is durable, easy to assemble, and reusable, so you can reconfigure and run new experiments again and again.

As you experiment, you can vary the weight of the car, adjust the slope, length, and direction of the track, and observe how these changes influence motion. This hands-on approach helps reveal how energy, velocity, gravity, and friction interact in a controlled, safe environment.

What you can build

• Working roller coaster models that move along real track
• Coasters of many shapes and sizes to explore different paths
• Engineering challenges such as the tallest coaster, the longest straightaway, or a loop-de-loop

How you learn

• Explore core physics concepts, including gravitation, potential and kinetic energy, and friction
• Study motion with variables like velocity, acceleration, and trajectory

In addition, a full-color manual guides every step with illustrated instructions and clear explanations of the science behind each design. The plastic building system is durable, easy to assemble, and reusable, letting you reconfigure and run new experiments again and again.

What’s included

• Durable plastic building system that is easy to assemble and reusable
• 32-page full-color manual with illustrated, step-by-step instructions

Versatility for classrooms, homeschool, and clubs: use this kit solo or in small groups to foster collaboration while students design, test, and compare coaster configurations. The modular pieces and durable construction support repeated setups and extended exploration beyond a single lesson.

Safety and practicality: the track remains flexible and the cars lightweight, making observations straightforward. The manual provides clear guidance so you can capture observations and refine ideas over time.
