Help to make co2 disperser-have co2 bubbler- now what?

Firstly, i'll say that i DID look for an already established thread on this first, so i'm just not askin without having looked.. Anyhaw i've seen i vids that youy can use the same co2 bubbler they use when making wine. Well , i bought one ,created a fitting to fit a 4 litre bottle and have baKING soda and prolly vinegar.
what else might i need and what would be the best way to use this, for those who have. Any help i welcome.

never seen this method to make co2 i remember the sugar water and yeast method lol try google man im sure there is something

Thanks you jdmcwestevo, i'll figure it out.
