College Students Create 'Frozen' Themed Prosthetic Arm For 9-Year-Old Girl

This 9-year-old was born without her right hand, but with the aid of a 3D printer and the dedication of college students, she's about to have a lot more fun the next time someone asks, "Do you want to build a snowman?" Students at Siena College presented Karissa Mitchell with a brand new 3D printed prosthetic arm, decorated to her favorite movie, Frozen. "It's awesome," she said, as she practiced opening and closing her new fingers around a stuffed Olaf. "It feels like I have a real hand."
