Iggy and Callum have been wondering how friction pens work .They have researching  how they rub the ink off your page and how it happens.

They found out how the gray end uses friction to rub off your mistakes; Its because when the dry ink is absorbed by the paper the gray end can use friction to rub the ink of sometimes leaving a black smear on your page. This how friction pens use friction pens to rub your mistakes off.
