Bloke Turns Lego Helicopter Into A Fully Functional Prosthetic Arm

This could be one of the most ingenious inventions of 2017, as teenager David Aguilar built himself a new rig for an arm out of nothing but Lego. 

What was originally supposed to be a toy helicopter, the clever 18-year-old from the small country of Andorra, turned it into a fully functional Prosthetic 'dream' arm.

"Lego helped me realise a dream I had when I was a child, which was having two hands," David said. 

In the video, David is seen completing mundane tasks he was never able to complete before.
