If you have no cooler or refrigerator then you have to improvise. A wood box will work but you have to line the inside with a cloth. The more layers of wood the better. Grass in the box around the ice will help too. Wood is a good insulator because it traps air between it's layers. Trapped air is the basic principle of almost all insulation.
It is generally recommended to place ice on top of the items in a cooler. This helps to keep cold air trapped inside the cooler, as cold air sinks and warm air rises. Placing ice on top also allows for more uniform cooling of the contents in the cooler.
You should remove the melted ice water in order to keep the cooler colder. As the ice melts, the water will start to warm up and reduce the overall effectiveness of keeping things cold. Drain the water periodically and add more ice as needed to maintain the temperature inside the cooler.
Since dry ice, which is frozen carbon dioxide, is even colder than regular ice (frozen water) it can be used to keep food cold for longer than regular ice does, when you take food with you in a cooler, on your camping trip.
An ice chest works by using insulation to trap the cold from ice, keeping the inside temperature low and preserving the contents. The thick walls of the chest prevent heat from entering, while ice helps maintain a cold environment inside. This combination helps keep food and drinks cold for an extended period of time.
Hard plastic, like the used in coolers. It is about the same material as a refrigerator. I did a project on this for another question, so I cut up an old cooler into a cube, then picked up some foam for a second layer over the cube, like the kind of material shaped in a box that you use to ship cold things in the mail.
To keep the beer in the cooler cold
The length of time a cooler can keep drinks cold can vary based on factors such as the quality of insulation, outside temperature, amount of ice used, and how often the cooler is opened. Generally, a well-insulated cooler with a good amount of ice can keep drinks cold for 1-3 days.
To keep a cooler cold for 5 days, use plenty of ice packs or frozen water bottles, keep the cooler in a shaded area, limit opening it frequently, and consider using dry ice for longer cooling.
To keep a cooler cold for a longer period of time, you can use ice packs or frozen water bottles instead of ice cubes, pre-chill the cooler before adding items, keep the cooler in a shaded area, limit opening and closing the cooler frequently, and use a cooler with thick insulation.
To keep a cooler cold for 3 days, use plenty of ice packs or frozen water bottles, pre-chill the cooler, keep it in a shaded area, limit opening it frequently, and consider using dry ice for longer cooling.
One way to keep things cold without a fridge is to use a cooler filled with ice or ice packs. The insulation in the cooler helps maintain a cold temperature for a longer period of time. Another method is to bury items in the ground, where the cooler underground temperature can help keep things cold.
To effectively keep a cooler cold for an extended period of time, you can use ice packs or frozen water bottles instead of ice cubes, pre-chill the cooler before adding items, keep the cooler in a shaded area, limit opening it frequently, and use a cooler with thick insulation.
Pour salt on it; it will postpone melting.
To keep the wine cold.
Put it in a cooler with ice or put it on the pouch as its typically cold at night.
To keep your cooler cold for a longer period of time, consider using ice packs or frozen water bottles instead of ice cubes, pre-chilling the cooler, keeping it out of direct sunlight, minimizing opening and closing, and using a cooler with thick insulation.
A cooler, insulated tumbler, or ice bucket can keep drinks cold for a longer period of time.
