How does newspaper keep chips warm?

Newspapers keep chips warm by providing insulation that traps heat. The paper's layers create a barrier that reduces heat loss, allowing the warmth of the freshly cooked chips to linger longer. Additionally, the absorbent nature of the newspaper can help to wick away moisture, preventing the chips from becoming soggy while maintaining their warmth. However, it's important to note that using newspaper for food wrapping has health concerns due to ink and potential contaminants.
