Hey. I remembered this thread after these years and after some new research and reading some other people's experiences with it in this site, I need to add that you should be careful with this method. It looks like the few seconds of agonizing are too much and it has failed for some people

Weird that the real life case study we had used says the death was instant and without suffering, because that's not like what happened in some cases I read about ... Maybe they didn't wait for the reaction to keep going for a bit? Because that would make low-ish concentrations of CO2, that are likely to cause bad side effects. But one should wait to get a high concentration to get KO'd more quickly. I'll look around for some more info
Two things to take into account are that someone said you might need to stir the mixture to make it react fully. Also you can have convulsions after the method and it can cause brain damage if it fails, so be careful
