Couple questions, would like opinions :)

Hi, AceTheKidd here and I have a couple questions for you guys. First off I wouldn't say I'm an experienced smoker, but I have been smoking for a few years now I have some questions that I'd like answered :).

1.) I would like to know if pressing and rolling joints ( not blunts ) makes the joint last longer and burn slower ?( allowing me to get the most thc )
2.) Can you make an effective water bong out of water bottles ?
3.) I have a dub an no bowl ( was generous and gave it to my cousin ) how do i make this last a while, at least till i get paid an re-up.
4.) Does the decarboxylated method really work in activating the THC and does it allow me to get higher, and will it smell up the house ?

So please if you could be nice and help answer these questions thank you :)

1.your burn time depends on 2 factors what type of paper your useing and how ground is it
they make papers that you can get at any smoke shop and not saying you should roll straight buds but you dont want anything that is like powder and if the buds are dry big possibility that this will accure
2.Attachment 289607 yes you can i made this one from a pomagranit bottle a socket sharpie and 2 of those tubes that i got from buying those candy cane tubes durring the holiday i know it isnt perfect but this was just a prototype and its a real chocker!!
3.just start smokng half bowls because you dont need a full bowl to get a good high or a few tokes from your joint but if you smoke on one joint for a couple days the taste isnt very plesant
4.decarboxylated it does work but it drys the cannabis out and will burn faster but dont know if it gets you higher and no it want stink upthe house unless your doing a couple pounds.

Cool thank you :)
