Why does pop get flat?

Pop has carbon dioxide dissolved in the water, hence, carbonated water which gives it its fizz. When that dissolved gas comes out of the water all you're left with is flat old water with the pop flavoring. How does the CO2 get in the pop? Well, gasses are soluble in liquids at either low temperatures and/or high pressures. As far as I know, pop is made at fairly cool temps and possibly slightly higher pressures. When the pop warms up or sits open to the atmosphere, the dissolved CO2 escapes and the pop goes flat.
