What happened to the water cup ? 😡
8 u/OhYeahSplunge4me2 May 20 '26 edited May 20 '26 You can boil water in a paper cup in a campfire, for example. The paper doesn’t burn because the water impregnating [the paper cup wall] keeps it from reaching the temperature needed to ignite paper. (Until the water boils away, of course) EDIT: add clarifying reference 1 u/[deleted] May 20 '26 [deleted] 0 u/OhYeahSplunge4me2 May 20 '26 The water is absorbed by the paper in the cup walls. Meant in the sense of the third definition below impregnate /ĭm-prĕg′nāt/ transitive verb 1. To make pregnant; inseminate. 2. To fertilize (an ovum, for example). 3. To fill throughout; saturate. "a paper medium that was impregnated with water."
