Thats alot of splices! Have you tested for leaks?
I usualy splice with only 1/4 or 1/3 overlap.

These bottles are available in the C1000 or Albert Heijn in the Netherlands, I have bought them too, they keep up with pressure quite good! I couldn't get more pressure than 10 bar howerver, my pump does not support that... yet.

@Willem What bottles are these? I'm from the netherlands to but I've never seen them.

@basrockets which glue are you using for the splices?

Hoi Arjan.
Deze flessen kon je vroeger bij elke supermarkt krijgen maar nu niet meer.( jaar 2006)
Je kunt ze wel nog steeds in Duitsland kopen.

Ik gebruik Bison 2 componenten lijm.

Are these more examples of the extra thick bottles?

No , after 2006 we also have thin bottles.
But before 2006 we had very strong bottles.

Only in Germany you can still get that bottles.
And the bottles that we got now just explode at 10 bar.

What type of beverage were those bottles made for? In the US we have some beer and alcoholic beverages sold at sports events that come in a thicker plastic bottle because those drinks generate more pressure. They make those bottles in shapes that are useless for water rockets, so there are few people who use them. The price of the beverages is typically many times more than they cost in the supermarket because at concerts and events they rip people off with high prices. The price makes it difficult to obtain enough bottles to make anything worth launching too.

I have experimented with plastic beer bottles before. They are strange. It looks is though they make them by layers or plastic to make them thicker. If you blow one up the layers come apart and it looks like they blow one bottle up inside another to make the layers.

The layers make the bottles hard to hold pressure when spliced they never seem as strong as a unspliced bottle for some reason. They are hard to shrink too!

We have seen some layered bottles in the past. It doesn't seem likely the bottles are molded twice because there would be no way to get the air out from between the layers, so the plastic preform blank bottles must be layered before they are molded.
