Basically, I read somewhere that boiling the water takes all the
oxygen out of the water which the yeast needs to get started.
Stirring vigorously should introduce oxygen that the yeast will
use to start the fermentation.

My water is very clean so it does not need to be boiled.
To get rid of chlorine, just pour off the needed amount
of water and let it sit overnight.

Using oxygen tanks or cylinders is better than stirring.
