A thin paper cup filled with water does not catch fire when placed over a flame because the paper cup does not become appreciably then the water it contain.
When paper cup is heated containing water, water absorb te heat coming from the burning sorce and thus prevents the paper from reaching its ignition point. hence it does not burn. Water in the cup becomes hot inste. This is due to absorption of heat by water.
