You swim in cold water, get out and then the afterdrop occurs. You are shivering and you want to get warm – warm from the inside out and from the outside in. You get dry, get dressed and grab that warm cup of joe, tea or chocolate.

But your hands are shivering, moving too quickly and uncontrollably. Your warm drink is splashing all over the place. A water bottle can resolve this problem – and so can the use of a drinking straw stuck in your cup when your hands are really shaking.
