Info: The bubbles are formed due to the fact that the sugar solution (coke) is stronger than the surface tension than water. Dissolved carbon dioxide when pouring begins to quickly stand out from the sugar solution, but because of the strength of the solution begins to foam. Ethanol acts as the classical antifoam by reducing the surface tension force and reduces the concentration of sugar in the solution.
