Video transcript

To keep things frozen in a cooler, pre-chill the cooler with ice or frozen gel packs before adding your items. Use block ice or large ice packs for longer-lasting cold. Pack the cooler tightly, filling any gaps with extra ice packs or crumpled newspaper to reduce air circulation. Place a layer of reflective insulation or an insulated barrier over the top before closing the lid. Avoid opening the cooler frequently to maintain the cold temperature inside.

Questions and answers

  1. What is the best type of ice to keep items frozen in a cooler?

    Block ice or large ice packs are best because they melt slower, providing longer-lasting cold compared to small ice cubes.

  2. How can I prevent a cooler from warming up quickly?

    Pre-chill the cooler, pack it tightly to reduce air gaps, use insulation layers, and avoid opening the lid frequently to maintain low temperatures.

  3. Can crumpled newspaper help keep a cooler cold?

    Yes, filling gaps with crumpled newspaper or extra ice packs reduces air circulation inside the cooler, which helps maintain colder temperatures.

  4. Should I place insulation over the items inside the cooler?

    Placing a reflective insulation layer or insulated barrier over the packed items before closing the lid helps reduce heat transfer and keeps contents frozen longer.
