DIY co2 not building up pressure?
thew together a diy co2, did 2 cups sugar, warms water and a teaspoon of baking yeast. ran it through an airstone, and got some bubbles, didnt last to long. poured half out did another cup of sugar warm water and more yeast, not much. poured most of it all out ran another 2 cups of sugar warm water and just poured yeast in. put a chopstick in the line and it wont buildup enough to push through. what am i doing wrong here?
