Burning QuestionScience brain teasers require understanding of the physical or biological world and the laws that govern it.
How can paper burn without any damage?
HintTry to rub out the problem.
AnswerSoak the paper in 50% isopropyl alcohol.
Then, the alcohol burns and the paper does not.
Alcohol molecules do not bond as tightly, so alcohol burns at a lower temperature than does 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.
