As a reliability engineer given the lack of details of their process I would be very concerned if someone tried this method as described. The lack of details given makes me feel like this is a bit of a jerry rigged or beta setup. Maybe I'm biased towards reliability, but I pretty much mess up all the Jerry rigged projects I try to do at home and end up having to revise multiple times to get right. I see the potential for inconsistent mixing and especially for capture and escape of the gasses, but am most concerned about potential long term issues from CO2 poisoning if it fails.
So I haven't dealt with chemistry since college and I am super tired, but at first glance the math behind the amount of chemicals being used to get to 25% looks like it's assuming almost perfect mixing of materials and not much loss in the capture of the CO2.
25% x 10 gallon bag = 2.5 gallons of CO2 *I'm making an assumption that a minimum of 2.5 gallons of CO2 are required for a volume of the 10 gallon bag, but there is likely a large decrease in bag volume due to head in bag... but I'm not going to go test this*
2.5 gallons = 9.464 liters
09.464 liters CO2 * 1mole/22.7 liters = .417 moles of CO2 gas required
stoiometric ratio is 1:1
.417 moles of Bicarb * 84 grams bicarb/mole= 35 grams bicarb
35 grams bicarb =
How many tablespoons is 35 grams of baking soda? How many teaspoons is 35 grams of baking soda? This page will convert 35 grams of baking soda to units of volume such as teaspoons, tablespoons, cups, and milliliters.

I'd also be hesitant to drink alcohol and then somehow manage to do this process without messing it up. And once again, I'm really concerned that if it fails (no death occurs), there will potentially be long term issues.
Also, I didn't check to see if 25% CO2 was a *verified* or *tested* value.
So I just thought about it and Carbon dioxide is heavier than oxygen & nitrogen and I am too tired to picture in my head what the setup would look like, but that's something that they don't describe how to deal with and I could see potential issues.
No, I will no go into further details. The point of my post is that this seems a bit sketchy, not to explain how to do it.
As a side note, I built a carbon MONOXIDE generator using off the shelf parts from home Depot and it leaked sulfuric acid and created noxious fumes and then I said fuck it, why am I doing this when I could just buy *reliable proven N*. So that's my frame of reference here.
