A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Which adhesive???

Post by r1ch » Fri Mar 11, 2016 12:37 pm

Hi guys, I'm in the uk and I need to know which adhesive is best to join my bottles together. I know PL Premium is most commonly used but I would need to import it and that is expensive. Any help is appreciated!

I live in PH and have the same problem. I use 24hr epoxy (Araldite, I assume) in replacement for the PL. Although it holds a lower pressure, it's a good alternative when using pressures below 120psi.

Thanks for the reply. I didn't realise it would be so difficult to choose the correct adhesive haha

Bison has some good glues. I've seen someone recommend this one:

Has anyone tried Gorilla Grab Adhesive?
It looks very similar to PL Premium, and more importantly you can get it in the UK!
