Tips and Troubleshooting

If the slingshot isn't firing far, then...

  • Make sure to grasp the back of the cup with your fingertips. Don't try to grab in your fist.

  • Pull back the cup so the rubber bands are stretched evenly.

If one of the dowels breaks, then...

  • Reinforce it by overlapping 2 or more new dowels like a splint.

If the rubber bands rip through the tape, then...

  • Reattach it with 2 or more layers of tape.
