Igloo-type cooler.
styrofoam, but warning fammable and unsafe for the environment!
To keep asparagus fresh for longer, trim the ends and place the spears upright in a container with about an inch of water. Cover the container with a plastic bag and store it in the refrigerator. Change the water every few days to maintain freshness.
Water gets freeze in a can rather than plastic container because plastic sis a non conductor of heat and chillness.

A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
To build a simple solar water distiller, you can use a container to collect water, a clear plastic sheet to cover the container, and a smaller container placed inside to catch the distilled water as it evaporates and condenses on the plastic. Place the setup in direct sunlight to heat the water and create condensation, which will then drip into the smaller container as clean, distilled water.
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
They take longer to get hotter and take longer to get cooler.
No because if you put hot water in a plastic container, it'll melt
