He built it out of plastic blocks and fishing line. 2 “Hello,” said a girl with an artificial arm, as she shook hands with Easton’s work. 3 This was the first time Easton met Jenny, a girl with a special condition. She was born without an arm. Her artificial arm was just a simple hook, but it cost $80,000. What’s worse, children like her grow quickly and need new arms all the time. 4 “It blew me away!

He stayed there all day. He always tried to improve his work. For his 16th birthday, Easton got a 3‑D printer. And with it, he invented an artificial arm. It was able to move with brain signals of the user. But it wasn’t good enough yet: the arm weighed 3.6 kilograms. It was too heavy for a child. 6 Easton kept working on it. He enjoyed fixing problems one after another. And finally he hit on success at age 23. His design only weighed 0.5 kilograms and cost around $500! 7 Easton’s invention has helped many children.
