When Steph and Jeff help Eddie into the kitchen, Steph places a bottle of Coke to the left of Eddie. In the next shot, the bottle is to his right. Then, the bottle proceeds to move from one side of the table to the other in the successive shots.
After Eddie opens the bottle of Coke in the kitchen, it fizzes up and spills. Then after Steph catches him cleaning it up, the bottle goes from having the cap off to having the cap on. Then, once Eddie sits back in the chair, the volume of the bottle fluctuates as does the location of the bottle cap.
