What could you do to make a gas dissolve faster in a liquid?

When you wish to dissolve a solid in a liquid faster, you increase the temperature. This makes the solid particles move faster and farther, and thus dissolve in the liquid faster. However, the problem with dissolving a gas is the opposite: gas particles already are moving fast and far, to the point where it is difficult to keep them stay in the liquid. The opposite is thus done, lower the temperature. A good example is a can of soda. Cold soda is almost always fizzier than warm soda because the carbon dioxide is dissolved more in the liquid.

cool the liquid and increase the pressure
