I seriously think this guy is a genius, possibly paving the way to affordable prosthetic limbs. Sun Jifa, a farmer in China, lost his hands when he was making a fishing explosive. He couldn’t afford the prosthetic arms at the hospital, so he found another solution — he built his own. Made of scrap steel, the metal arms use wires and pulleys controlled by his elbows.
Sun said the only downside is that it gets quite hot in the summer, and the metal can be quite heavy. Check out the amazing pictures below of his highly functional hands. “‘I made this from scrap metal for virtually nothing,” Sun said. “There is no need to pay hospitals a fortune.”
