I find your question interesting, although some may say "what?" who cares. Actually your question is very interesting and I am sure it ties into science and molecular makeup and chemical reactions of the liquid (soft drink) and the carbon, along with the solid of the straw.
Do you know what I see here, and I don't have the answer. But I see a great science project here for school. You can compare the air bubbles in the straw of soft drinks, vs. plain water and blowing bubbles into the water. Do the bubbles in the plain water stick to the straw like the carbon bubbles in the soda? If yes, why, if no why.

It may be due to the fact that the straw is warmer than the liquid and heat exchange occurs causing bubbles to form as adjacent liquid is warmed. The bubbles incidentally will be carbon dioxide. The bubbles will rise only when surface tension is overcome by buoyancy effects.

when talking about fluids (both gases and liquids are considered fluids) there is something known as the no slip boundary condition. This states that at the boundary between a fluid and a solid object the velocity at which that fluid moves is zero.

Possibly due to the attraction of unlike substances. A process called "adhesive forces", or adhesion.
[as apposed to the attraction of like substances, called "cohesion."]
