Marvel’s superheroes seem almost as competitive off screen as on, at least when it comes to their charity work. With coordination through Microsoft’s Collective Project, Robert Downey lends his support to Hand-a-Thon volunteers who design, assemble and donate prosthetic arms for children. Thanks to 3-D printing, the volunteers at the University of Central Florida built 60 arms in just one day.
Naturally, the video’s adorable.
Here’s a segment highlighting the Hand-A-Thon event at UCF.
