hmmmm with 2 litres i'm not too sure how much to add but i usually add twice as much soda compared to yeast.... hmmm maybe try 1 teaspoon soda and 1/2 to 3/4 teaspoon of yeast....just try this as a start first and monitor the co2 output then from there you adjust the proportions of your mixture. have to keep trying to find the right proportion.... all the other bros are still sleeping perhaps you'll have some more help by then
btw i'm a girl
