Frozen water bottles vs ice packs vs cubed ice: Frozen water bottles are the most practical choice

Frozen water bottles last longer than cubed ice because they’re a solid block with less surface area, and they’re cheaper than reusable gel packs since you can drink the water when they melt. Dry ice lasts longer but requires handling precautions and isn’t always available. For everyday use, frozen water bottles are free or nearly free and add value even after thawing.
