I am wondering how I could calculate the drag coefficient of a regular 1.25L coke bottle. I used it as a submarine, and found its acceleration, compared to what its acceleration 'should' have been'. I am comparing the missing force between the theoretical and achieved accelerations to viscous drag force, but I can't find the drag coefficient for a 1.25L plastic bottle.
