Good Cheap Co2
Recently I have been thinking about how to completely seal my co2 in the bottle, if you go to a local winery were they sell the yeast and supplies for wine making you can get a wine bottle and rubber cork with a hole in it. With a piece of airline tubing in this hole it is completely sealed, also the mixture changes is much easier. While your there ask the people what kind of sugar creates the smallest co2 bubbles ( there is a big difference from home sugar to this stuff ) I believe its called barley sugar. Works Great and came out to about 10 bucks for everything.
