If I get the idea right, you force air into the bottom of the bottle (with the fish tank air motor) and that causes the pressure inside the bottle to build, and forces pop out the other tube. My guess is that it only works until either the carbination disappears, or the pop level gets to around 1/3 of the bottle.Seems like a neat thing for kids. Might build this! Thanks!!
