Just when you think a celebrity can't get any cooler, RDJ surprises a worthy kid with his very own Iron Man bionic arm!

Not gonna lie, it almost hits you in the feels.

Collective Project student Albert Manero is the artist who made this bionic arm. Chances are you've heard of him in the past too. He's the awesome guy that 3D prints prosthetic limbs for people, completely free and on the cheap. He founded Limbitless, his own charity to do these types of projects.

Now this was all done as a part of #CollectiveProject. If you'd like to know more about an admirable group of people, click here.
