just bought an old soda siphon from a yard sale...help!
Over the weekend I bought a cool blue metallic soda siphon for $3. I've never used one before, so I have some questions...
1. can I use old co2 cartridges? It came with a box of 10, but 9 of them have already been used, which are obviously garbage. There's one that still has the seal in tact--can I use that one? I have no idea how old it is, but the picture on the box looks pretty 70's-ish
2. The box of cartridges that came with it are some German brand--Berndorf Kayser. I bought some Isi brand ones because they look exactly the same. Should be ok, right?
3. what's the screw at the top for? if I unscrew it, it has a spring attached to it.
There's just something about the CO2 that makes me nervous!!! anything I have to be really careful not to do?
I've looked at a youtube video, so I know to shake it after it's been filled and to use cold water, etc. but I was surprised at how few videos there were on them.
Thanks for any help!
