I usually microwave an ice pack for 30 seconds then rubber band it around the thermos.
A plastic cup will not keep hot water warm for a significant amount of time. It is not an effective insulator and heat will dissipate quickly. It is recommended to use a thermal mug or a container specifically designed to keep beverages warm for longer periods.
Animals use sunlight to keep warm, to see, and some use it to make vitamin D. Plants use sunlight to keep warm and to make sugar from carbon dioxide and water.
Fooding warming trays keep food warm by applying heat to a small amount of water in a tray underneath the food tray. The tray containing the water is heated either by electricity or with small alcohol gel candles. The heat and steam radiated up from the water and tray holding the water keeps the food warm.
Sea otters are adapted to keep warm by its thick and dense fur. It has two layers of fur; one a water proof guard layer, and then a shorter layer of fur underneath. Unlike most marine mammals, they do not use blubber to keep them warm. So they use their fur instead.

Yeah you can, as long as you keep the water you use at a warm tempurature, dont use a hairdryer or anything because it will scare it and may cause frustration, i'd just use a towel to dry them n keep them warm =) hope this helped
Take it out of the ice chest. A plastic insulated cooler can be used to keep things warm. Warm the cooler by running hot water into it. Empty the water after a couple of minutes. Wrap the item you want to keep warm in newspapers or towels and place it into the cooler. You can also use something that can be warmed, such as the combination ice/hot packs, to pack with the item in the cooler and it will help it stay warm longer.
To keep food warm for hours, use an insulated container or a slow cooker on a low setting. Additionally, wrapping the container in towels or using a hot water bath can help maintain the temperature.
some kind of are. Sea turtles and sea snakes use the water and sunlight to keep warm or cool down.
To insulate : To keep warm things warm and cold things cold
