Alex Pring was born with a partially developed right arm, but he still loves everything all boys his age do, like riding his bike and super heroes.
"Some people would say what happened to your arm? Or how did that happen and all that bad stuff. I don't like it. It makes me feel very bad," Alex said.
Enter Iron Man.
Robert Downey Jr., aka Tony Stark aka Iron Man, helped turn the 7-year-old into a real life Iron man thanks to a college student. Albert Manero builds and donates low-cost 3D printed bionic limbs to kinds around the world.
Last week, thanks to help of the Collective Project, Iron Man and Pring got to meet and Downey gave Pring the bionic arm.
Iron Man and Pring both tried their arms on gave them a try. Watch the moment Iron Man and Iron Boy put their arms to the test above. App users, click here.
