Tips and Troubleshooting

If the spinner isn't spinning for very long, then...

  • Make sure to pull down quickly and in a linear path. Pulling slowly or off to the side won't work.

  • Tilt the launcher forward as soon as the string releases from the spinner.

If the wheels or cable tie are sliding around the dowel, then...

  • Apply a small amount of glue where the wheel hub or cable tie touches the dowel.
