1 Easton LaChappelle, a 14-year-old student, stood beside his work at a science fair. It was a robotic arm. 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! I built my arm for only $300," thought Easton. "I must lend a hand to people like her."
1.What did Easton make at the age of 14
A robotic arm.
2.What was it made out of
It made out of plastic blocks and finishing line.

5 After the fair, Easton's room became a lab. 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!
