Picture of Water Rocket Bottle Splicing
Introduction

This tutorial describes how to splice two bottles together when you only have bottles of the same size. Splicing bottles allows you to create larger capacity and longer water rockets. Although this tutorial shows how to splice 2 liter bottles the same technique can be applied to other bottles with straight sides. The same technique can also be used for multiple splices in the same pressure chamber. At the end of the tutorial we add reinforcing to the bottles in order for them to withstand higher pressures. If only lower pressures are required then the reinforcing is not needed.

Materials
  • 4 identical 2L bottles with straight sides.
  • Sikaflex 11FC glue
  • PL Premium glue
  • Glass Strapping tape (optional)

Tools
  • Hobby knife
  • Scissors
  • Electrical tape - used as masking tape because it is flexible and stronger than regular masking tape.
  • Sandpaper
  • Mineral Turpentine
  • Thermometer
  • Skewer stick

Step 1:

Amazing Acts of Science brought me to this page! I saw it on the show and I have to do this now before the Summer ends! Thanks for posting.
