i learnt about a DIY
project of CO2
injection from the net.. and it has been three days after the day i mixed all the stuff together ( 3 cups of sugar and 1/4 teaspoon of yeast) and put em inside a closed 2 litres bottle.
there are very few bubbles coming out of the tube (bout 2 bubble within 5 mins) and in order to make the yeast mixture release more bubbles, i have to shake it or put the bottle inside a warm pail to make the mixture warm.
is it ok if i do all those things (mix and make it warmer)? it has been three days and still so few bubbles.. does that mean that the project is not successful (maybe the yeast's dead?)?
in order to collect most of the bubble so that it won't evaporate directly on the air above, i put a trap (actually it's a bottom of a 500 ml bottle) on top of the end of the tube so that it can trap the air.
will it work better if i put the trapper above it? because i think more CO2 can absorb into the water that way..
