That is unlikely to work. Centrifugal separation works when the fluid you're trying to separate is a suspension of either solids or multiple fluids that do not mix (such as oil or another fat and water). Blood is a suspension of several types of several things (red and white blood cells, platelets, minor amounts of other stuff) in plasma, so you can separate each of those components out with a centrifuge. Soda, unless it contains something like fruit pulp or dairy, is generally not a suspension and therefore will not be separated by a centrifuge
