Three bottles I tried to connect together. The middle one has gotten the same treatment as our 2x2liter bottle: I put both ends shortly into boiling water, causing the ends to shrink a bit, so they fit snugly into the two other bottles. Then I crammed rubber strips (from an old bicycle tire) into the joints to try and seal them. The biggest mistake was using a flame to try and melt the stuff toghether: the rubber does nothing at all and the bottles start to shrink in all kind of funny ways.

Need I tell you that the thing leaked as soon as I poured water into it?

The 2x2 liter bottle was filled with wallpaper glue to try and seal the leaks. Here the excess glue is dripping out of the rocket inside a recipient (which is, of course, another bottle with its top removed).

I repeated this step a few times, even putting pressure on the bottle when the glue was inside, so the glue was pushed in all leaks. This thing held to about 2 bar, which is not that much of course.
