5-year old Keith Harris got to share the coolest "show-and-tell" item ever, thanks to 3D printer technology and his new prosthetic hand.

Keith, who lives in League City, Texas, was born with an underdeveloped right hand due to a condition known as symbrachydactyly. He was recently given a prosthetic hand made by a 3D printer. Showing off his new hand to his kindergarten classmates put a huge smile on his face. Check out the smile on Keith's face in this KPRC-TV report as he high-fives his friends.

As the report states, Keith will need therapy to learn how to use his new hand, but that little man and his mom are excited over the possibilities his new hand brings.
