My answer for the glass half full problem is that there will be more lime in the cola. I came to this answer from a mathmatical stand point. When you put the lemon lime in the cola its 100% lemon lime. Then when you trasfer the same amout back to the lemon lime it not 100% cola its diluted with lemon lime, so therefore theres more lemon lime in the cola glass.
