The term 'Drink Cooler' can be broken down into two crossword solutions: ICE (3 letters) and ICECUBE (7 letters). An ICE cooler is a device used to keep drinks cold. It typically consists of an insulated container with a lid, filled with ICE or ICE cubes. The ICE helps to keep the contents of the cooler cold for a longer period of time. ICE cubes are small pieces of frozen water that are used to cool drinks. They are usually made in a tray and then placed in a freezer until they are frozen solid.
