Just get some tubing (the name escapes me at the point in time) and you can push it onto the pipe on the soda stream machine. No fittings necessary then.
Have a look here:http://www.aussiepythons.com/forum/diy-zone-5392/co2-gas-chamber-instructions-94534/
The pictures on the main post are gone but there is a picture of a complete setup further down on the first page
I use thin, flexible irrigation tubing that you can buy from Bunnings or similar place. I have a pretty old soda stream machine though, dont know if other machines have the same slim outlet. But anyway places like Bunnings has all sorts of flexible tubing.
i just use fish tank air line, picked up 2 meters for $2 at my local aquarium, still got plenty of it left. it fits tightly over the soda stream outlet, but can be removed so the soda stream can still be used to make drinks.
Using the whole machine is much simpler. You just pull it out of the box, attach a hose and you're ready for some gassing! You can probably get fittings for the bottles but it's totally unnecessary. Plus like others said, you can still make soft drinks with it if you leave it intact
Can someone please explain what we are gassing and why?is it rodents?is that how you put them to sleep/kill them?i hope that what you are talking about.
Thanks saximus,i was hoping to find this info out but didn't want to seem gory.for rabbits too.....hmmmmmm......we just got a rabbit,may need another one..a boy.
