Straw Rockets
Design and launch a lightweight paper rocket with air from a straw, then revise its shape for distance, accuracy, or stable flight.
What You Will Create
A flexible, hands-on build.
Design and launch a lightweight paper rocket with air from a straw, then revise its shape for distance, accuracy, or stable flight. The guide can be adapted for families, classrooms, clubs, or drop-in learning spaces.

Supplies and preparation
Supplies
Gather these materials
- Paper
- Drinking straws
- Tape
- Scissors
- Measuring tape
- Markers
- Paper clips for optional weight
Preparation
Before participants begin
Create a clear launch lane and mark a start line. Prepare paper tubes that fit loosely over the available straws.
Launch only toward an open area and never toward a person. Each participant should use a personal clean straw or a separate launcher sleeve.
Build Guide
Follow the steps
Test as you build. Small revisions are part of the process and help participants understand why the final design works.
1. Plan and prepare
Wrap paper loosely around a straw to form the rocket body and tape the seam.
2. Build the foundation
Seal the front end completely so air cannot escape.
3. Add the main feature
Add small fins near the open end, keeping them even and aligned.
4. Test and adjust
Slide the rocket onto the straw, aim down the clear lane, and blow once to launch.
5. Finish and reflect
Measure the result and revise one feature such as fin size, body length, or nose weight.
Keep Exploring
Try another direction
Use one of these extensions after the first version is working.
- Compare two fin shapes.
- Build for accuracy toward a floor target.
- Record three trials and calculate an average distance.
LEARNING CONNECTIONS
Ideas within the build
Learning Connections
Ideas within the build
Air pressure, aerodynamics, stability, measurement, variables, data, and iterative design.
Facilitator Note
Make the process visible
Ask participants to predict what will happen, test one change at a time, and explain what they revised. Photograph early and final versions so the improvement process becomes part of the project story.
