WATCH: Heart-warming video of Iron Man giving young Alex his bionic arm

Iron Man a.k.a. Robert Downey Jr. paid young Alex a very special visit this week. Alex is a seven year old boy who loves super heroes and riding his bike. He was also born with a partially developed right arm. Albert Manero, a #CollectiveProject student who founded Limbitless, arranged for Downey Jr. to surprise Alex with a new bionic 3D printed arm at no cost to the family. Visit here to learn more about the amazing work Albert and the #CollectiveProject do. https://www.youtube.com/watch?v=oEx5lmbCKtY
