How-to Homemade C02 ?

[melodious fellow]

I have heard of people mixing yeast, water, and sugar to produce C02 as well as others using carbonated water.

Can anyone explain these methods in more detail... amount yeast etc. to mix, how to administer

With carbonated water, just water plants like normal with it or leaf-feed?

If anyone has any other cheap, easy, or homemade methods of administering C02, that would be much appreciated.

Yeah i'm also wondering if these examples do anything, but either way i am going to give the yeast thing a try, i will mix up a 2litre bottle of 1/2 warm water, 2 tablespoons salt, and 4 tablespoons sugar.......and i have no experience with this at all but i know that the mix i said will activate the yeast and produces gases i just don't know the effect.Another thing is, i am going to place the bottle just above my plant and i will attach a hose to it pointing to my plant because i beleive c02 is heavy than air, then bring the co2 down the entire plant, and again i don't know if this works, i'm just gonna try it.
