how u make yr CO2? in how many liter of bottle?

exampl for 1.5L of bottle, you need at least 8 table spoon of sugar, 1 tea spoon of yeast and 1/2 tea spoon of soda powder. Melt the sugar with warm water...then yeast n soda... shake it. yeast will be more active in warm water. (not hot or cold water. Hot water will kill the yeast)

soda powder is to increase the speed to get the mixture done. Once the CO2 coming out..it will be very strong for 1st 2 days...then it will getting slower on 4-5 days.

u can get 1 way valve in any lfs. just tell them the connector which can connect to the hose(the hose which is we using for air pump). and the connector only 1 way in and 1 way out...
