Iron Man With A Certain Little Man

 Seven year old Alex Pring became ABC News' Person of the week this past week; Alex was born with a portion of  his right arm missing but has always remained optimistic throughout. So in a big surprise he got to meet Robert Downey Jr. (Iron Man) who presented Alex with a bionic arm made out via 3D Printing. The arm was desgined by Albert Manero and his engineering team from the University of Central Florida. It's a really touching moment to see how special young Alex is and how he shares such great characteristics as a real life superhero.
