I made it about 3 hours ago and i'm not getting a single bubble in my bubble counter. How long should this take? It looked like it was rising in the bottle but now it's all settled down again. That DIY thread is all over the place and dude forgot to say how much water so idk what's up but nothing is happening. Instead of using a 2 liter I'm using 2 1 liters that way I can keep changing one of them out and it will always stay constant. I put 1/2 tsp of yeast and 1/2 a cup of sugar and 1/2 a tsp of baking soda.
