It's a school material that rocked our childhood. Do you remember that? This is obviously the mythical pink and blue gum. We thought the last part was used to erase the pen. Discover the true usefulness of this mysterious half that has not been elucidated, even in adulthood.

Relayed by our colleagues at CNews, the role of the blue part of this gum finally lifts the veil on all our questions. And for good reason, the intrepid who tried it tore their sheet. No, this bluish half doesn't erase pen ink at all, contrary to what everyone thinks. 

What is the use of the bluish part of the gum?

Unbelievable, isn't it?
