Cola, also known as Coke, was a drink found in the world of Cittàgazze and Will's world. Lyra Silvertongue first tasted it in Cittàgazze, as it didn't exist in her world. Will Parry showed her how to open it, and when it opened it frothed at the top. When in the cinema in Oxford, Lyra tried some with hot dogs and popcorn.
