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.
