Burning Question
How can paper burn without any damage?
Hint
Try to rub out the problem.Answer
Soak the paper in 50% isopropyl alcohol.Then, the alcohol burns and the paper does not.
Alcohol molecules do not bond as tightly, so the alcohol burns at a lower temperature than the paper. You can add NaCl (sodium chloride or common table salt) so it will burn with a yellow flame, and make the flame more visible.
