Beverage Insulator

To keep your favorite beverage cool, convert an inexpensive vacuum container. Discard internal lid if equipped. Center and drill a snug hole in the cap such that the bottle is firmly held. This will reduce condensation on the inside and slow heat transfer even in the hottest environment.
