How to Stabilize a Model Rocket

It's fun and educational to build a model rocket, but you have to make sure it's stable before launch.

Difficulty: Moderately Easy

Instructions

1. Balance the rocket sideways on your finger. The point where both sides balance each other is your rocket's center of gravity.

2. Tie a 7 foot string to the rocket at its center of gravity.

3. Spin the rocket in a circle while holding the string. If it's stable, it should point forward while spinning.

4. If the rocket is unstable, add more weight to each side until it becomes stable. This is a tedious process, but it's worth it to see your rocket fly as high as possible.

Tips & Warnings

• Make sure your rocket's motor is on when you calculate its center of gravity.
