Big Bertha® is one of Estes’ most enduring designs and has introduced generations of students to the thrill of model rocketry. Its large size and stable flight make it easy for learners to follow from ignition to recovery, helping them clearly observe each phase of flight. This visual clarity makes Big Bertha especially effective for teaching core aerospace concepts in an engaging, memorable way.
Designed for Confident, Predictable Flights
The rocket’s slow, realistic liftoff allows students to clearly see thrust in action as it leaves the launch pad. Powered by standard Estes engines, Big Bertha can reach heights of up to 500 feet while maintaining excellent stability. The large 18 inch parachute ensures a gentle descent, increasing the likelihood of successful recovery and allowing for multiple launches during a single class session or event.
Hands On Learning With Quality Materials
Big Bertha is built using durable Estes body tubes, laser cut balsa wood fins, and a molded plastic nose cone, giving students experience working with real model rocketry components. Applying waterslide decals adds a creative element that lets learners take pride in their finished rocket while reinforcing attention to detail and following instructions.
Ideal for STEM Lessons and Group Programs
This rocket fits naturally into lessons on aerodynamics, forces and motion, and engineering design. Its compatibility with commonly used classroom launch systems makes planning and setup straightforward for educators and group leaders. Whether you are running a single demonstration or guiding multiple student builds, Big Bertha delivers consistent results and lasting educational value.
A Rocket Students Remember Long After Launch Day
For many learners, Big Bertha becomes their first “big” rocket and often the one they remember most. Its impressive presence on the pad and dependable performance help build excitement and confidence, encouraging students to continue exploring STEM subjects beyond the classroom.
