Stabilizing DIY CO2
I built another DIY CO2 generator after I got fed up with having two soda bottles. The new one I built is made from a large 4 litre juice jug and it works great, but I have had mixed results.
I have been using the jello recipe because I thought it would be more stable. I add 4 cups of boiling water to 4 packs of jello, then I add 4 cups sugar and water. I put the jello mixture in a big glass casarole dish and cube it when it sets and then into the jug. As for the yeast, originally I added 1 tsp but after about a week the yeast fizzled and died, I think as a result of too much alcohol being produced. So I reduced the amount of yeast to 3/4tsp and I also added another cup of water with the yeast to help dilute the alcohol. This mixture is producing just as much, if not more and it hasn't faded out like the first one. I have had one reoccurring problem though, the mixture will stop producing a consistent stream of bubbles and instead will let off huge bursts every thirty seconds. Has anyone else had this issue? For the life of me I can figure out why it does this, sometimes for days.
With this setup I have been able to get pearling to occur and my bubble count must be around at least 2 bubbles a second. Honestly I stopped counting when I got to 80 bubbles a minute. Overall I would consider my new CO2 generator to be a success, but I would like to further stabilize the bubble production. I have been using bakers yeast until now, but I think I will try champaign yeast next. Does anyone have any further suggestions on how I could enhance the mixture?
