Introduction: Slingshot Straw Rockets - Engineering Projects for Kids
Simple and inexpensive to build. The slingshot rocket may take a little practice to use, but the payoff is well worth it as you launch it over 50'!

Step 1: Tips and Troubleshooting
If the rocket is colliding with the stick, then...
- Make sure to follow the launch technique that's shown in the video: hold the stick upright, and allow it to flick forward upon release.
- The fins may be too large, or attached at a very crooked angle. Redesign the shape, size, or position.
- You might be using a short rubber band. Longer rubber bands help avoid this collision.
If the rocket is not flying very far, then...
- Stretch out the rubber band more before launching it.
- Aim upward at a 45-degree angle before launching.
- Make sure to follow the launch technique that's shown in the video.
If the rocket is not flying straight, then...
- The fins are probably attached at a crooked angle. Remove them, and carefully reattach them so they are as perfectly straight as possible.
