I know, I make my own seltzer (first with a DIY setup and now with a hacked sodastream). I get them filled at the fire extinguisher place for $20. I have a 10# that I can test with though ideally if a paintball sized bottle would work they are cheap to refill. My guess is a 5-10# is needed. I think paintball ones are less.
Anyhow, checking the mail - no sensors today.

...My pet peeve is a good thread with no conclusion because the OP solved the issue and disappeared. Either that or bus fatalities are much higher than reported.
