Elementary education is a threshold for a prosporous future ahead. Itâs even hard to imagine that a 20-year-old full-time farmer, owing to his memories of middle school physics lessons, has built himself a helicopter that he claims can go as high as 800 meters.
Wu Zhongyuan, from Chinaâs Henan province, made this helicopter by using a 150cc motorcycle engine providing power to those wooden blades (made from elm wood) while its structural rigidity comes from steel pipes/tubes. Spending about three months and nearly $1600, the government finally played spoilsport by stopping the flight for safety reasons.
