ICYMI: The amazing 9-year-old 3D printer

UPDATE: This video has been removed at the request of Wareness.

Today on In Case You Missed It: 9-year-old Calramon Mabalot could probably teach a STEM course, since he just 3D printed a prosthetic arm for a teacher. The whole story only touches on the charm that is this kid's YouTube channel. If he's the future, we'll be alright.

We also briefly played Lego Donald Trump and followed that with a palate cleanser of a video: A dog who is afraid of a windshield wiper. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
