Thermal bag
A thermal bag is like a special magic bag that keeps your food or drink hot or cold.
When you put something inside the thermal bag, it traps the hot or cold air inside and doesn't let it escape. Just like when you wear a jacket, it keeps your body heat inside, making you feel warm.
The thermal bag has a special lining inside that helps to keep the hot or cold air from escaping, like a blanket around your food.
Once you put your food or drink inside the thermal bag, it helps to keep the temperature the same as when you first put it in. So, if you put hot soup inside, it will stay hot even when you take it out later.
You can take your thermal bag with you wherever you go, like to school, on a picnic or on a trip. It's very useful and helps you to have a yummy and refreshing snack or meal whenever you're hungry or thirsty.
