| | Re: Whats the biggest DIY CO2 bottle you can make?
I used 3-liter soda bottle before. To compare to 2-liter bottle, I used the same amount of yeast with 150% of the sugar and 150% water. The intention was to get proportional increase in time (last longer). That is it would produce the same amount of CO2 (bubble count) and last 50% longer (3 weeks instead of 2 weeks). The result: No change. Unscientific conclusion: Most of the yeast can probably only last for 2 weeks in that environment, does not matter how much more water or sugar added.
