Iron Man brings 7 year-old new bionic arm

Robert Downey Jr. is winning social media this week by reprising one of his best-known characters, all for a good cause.

In the successful "Iron Man" and "Avengers" films, Downey Jr. plays Tony Stark, a billionaire inventor who designs a wildly expensive suit of armor.

Stark (Downey Jr.) recently paid a visit to 7 year-old Alex on behalf of the Microsoft-backed Collective Project, which showcases the efforts of college students to improve the world. One of those college students is Albert Mareno, founder of Limbitless Solutions, who's designed bionic, 3D-printed arms that cost just a few hundred dollars. Tony, a "bionics expert", is fully behind the effort and presented Alex with his own, Iron Man-themed arm, in this fantastic and heart-warming video.

Despite the fact that Tony's arm didn't quite work as well as Alex's, nobody seemed to mind.

Job well done, Iron Man.
