Here is how I did it... warm tap water in 2 liter bottle, added 2 cups of sugar and 1 tsp of baking soda, shook bottle till sugar dissolved, then added 1/4 tsp of yeast, shook again, then filled bottle (about 3-4 inches from top), shook a second or two more, then placed it. I have been seeing tiny bubbles throughout the bottle coming from the bottom upto the top, so as stated above I am hoping by morning/noon all has turned out well....
