I used some of the 1 gallon CO2 containers until one blew up on me (what homebrewer hasn't had an accident?). It blew my head clean off. Fortunately for me, my dog, Barleycorn, put my head right back on, or I should say, wrong back on and it was only after I ran into a couple of things that I knew it was backward.
We, Barleycorn and me, made the correction and you have the person now before you, apparently none the worse for the wear aside from an occasional fixed stare into the distance for an indeterminant while. Barleycorn, thinking maybe he is a fault for this state, keeps a close eye on me during these episodes. Although, once I came out of it before he was ready and he had my bottle of ORVW 15 YO up to his mouth. That brought me back to full consciousness forthwith. He claims he knew that it would and that is why he resorted to 'faking' it with the Old Rip! Damn dog lies through his teeth. I have told him repeatedly that lying will get you into trouble...........'Yeah', he says under his breath, 'you ought to know'!
We never told my wife that I had temporarily lost my head........she would have found it completely in character anyway!
Do not go gentle into that good night,
Old age should burn and rage at close of day;
Rage, rage against the dying of the light. - Dylan Thomas
