2-liter bottles
You would most likely be best off building your own chamber sealing valve. Theres a really really easy tutorial at bcvids.com

Do you have any idea how much recoil a 2-liter bottle launcher has?
Loads, as our freind DR <a href="http://forums.spudtech.com/topic.asp?TO ... relates</a> to us.
As I suggested in that thead, I suggest a recoilless design here - but with one change; build the cannon inline.
Such a design (inline) would eliminate the need for any fittings, thus cutting the cost significantly.

Why not make it to shoot 600mL bottles? They hold a bit more than cans, and they have a lid so you can drink them then fill them with whatever you like.
I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

dont fill the bottle up with anything when you shoot it just water because i have a 2 liter bottle rocket launcher that i designed and built and me and my friends decided to put shredded cheese into the bottle
and i made the launcher so that you have to pull down a section of pipe that holds the bottle down and when i pulled it shredded cheese sprayed on my hand and it stung i had like 100 little welts on my hand for a week and i only had pumped it up to 60psi it felt like gettung shot by an air soft gun in the hand 100 times.
