How to remove black blue ball point pencil pointer ink from paper

This pen uses heat to erase ink. | Insider Design

DON'T TRY THIS AT HOME! Can we really remove a doodle with fire? Spoiler alert: we can, but only when using special pens that use thermo-sensitive ink. When heat is applied, that ink disappears. You can do this with a match, lighter, or even an iron to erase a whole page of writing! If you use a regular pen, the writing will not disappear after using flame on it, unless you burn your piece of paper completely! #TheDadLab #scienceexperiment #dontbefooled | TheDadLab
