splicing bottles for water rockets - clear pet plastic sheets

Splicing bottles together is a technology often used by water rockers to increase rocket volume.
Splicing involves bonding the parts of the bottle together to make a longer pressure vessel.
Due to the power involved in the interior of a typical rocket, and the PET plastic is difficult to glue, there are only a few existing glue suitable for the job.
The most commonly used is the PL premium construction glue, but it is also possible to use the vise and a small amount of other adhesive.
Splicing is not as easy as using Robinson coupling to connect bottles, is permanent and not easy to predict under pressure, but it has the advantage of almost unlimited internal flow, and it is possible to create potential long pressure bodies in this way.
The technology presented here is based on the previous work done by other rockers: The following video tutorial we present a technique called "symmetrical fragments" for connecting two bottles.
The same technology can be used to make longer bodies.
The connection is repeated for each part.
