Max Wilford is a little boy who is battling a rare form of brain cancer.

Max's classmates, teacher and principal are joining together. They're trying to make the world’s longest Rainbow Loom chain for Max.

Jimmy Kimmel invited Max on his show wearing a special suit of the loom. Jimmy will auction the suit of the loom for the Max Love Project which helps children with cancer.

Check out the video below and watch Jimmy get choked up towards the end... Warning you may also need a tissue..
