How can paper burn without any damage?


Soak 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.

Kids: If you try this, have a parent or guardian to help!
