Tips and Troubleshooting

If the launcher isn't shooting very far, then...

  • Make sure the rubber bands are being stretched out enough.

  • Make sure the clothespin is positioned at the top of the craft stick "stairs." If it's not, the cork or the rubber band may get caught on the edge of a stick.
