This video footage shows Robert Downey, Jr. present a bionic arm to a seven-year-old boy named Alex, born with a partially developed right arm. The arm is free of charge to Alex and his family, courtesy of Albert Manero and the Collective Project, which makes and donates bionic limbs to children in need across the globe. It's safe to say little Alex, who recognizes that he's getting a bionic arm from Iron Man himself, is having a great day.
