In one book I read about boiling water in a paper cup. Actually I tried heating a water in a paper cup till it becomes hot. Paper did not burn. I am interested to know the principle behind it.

 

Similarly one more article in the book says If you roll a pencil with paper and heat it in a flame paper does not burn ( This I have not tried)

Well, paper burns at 451 degree Fahrenheit, and water boils at 212 degrees Fahrenheit.

 

depends how he heated it up, and what paper he used.
