Step 8 Splicing

How to splice

To join two bottles together like in the picture to create an air tight seal you need three bottles

first cut the bottom ends off two of the same sized bottlles

Then cut both ends of the same sized third bottle and place that in the two exposed ends of the bottle

Next glue the third bottle in the 2 exposed ends.

What kind of glue should I use

[oscarthompson]

I used bostik soft plastics glue and it works fine for me. Although you can use PL premuim, but this is a bit more expensive and harder to get hold of in the UK, but it may give you better results.
