Cold soda in a glass, add ice while trying to agitate the liquid as little as possible. Cold liquids have greater capacity for dissolving gasses. It is less prone to release boubles. Use an ice machine for your ice. Smooth ice has fewer nucleation points for the co2 boubles to form. Cold, slow and smooth. Expect to loose some carbonation. In the cases i have very rugged ice from the freezer, i sprinkle some soda or water on them to melt the outer layer before adding my drink slowly.
I read something about some resarchers looking at what goes on in the brains of elephants when interracring with humans. They concluded that it was similar to the reaction when humans encounter cute things. Was a really long time since i read that. So take it with many salts.
