More than 10,000 kids from China and abroad took part in the Science and Technology Exposition for Youth in Shanghai。The four-day exposition displayed more than 150 inventions and other high-tech devices。It wanted to open science communication channels between children from different school and countries。
Ten-year-old Chen Wenqi and Tao Yun from Gonglu Central Primary School,said the site was like a playground with robots and fancy machines all around。“I like the robot most ,and hope I can invent something like that one day,”said Tao Yun 。 Two high school students showed off their Lego machine,which can count and wrap coins with the help of piping,steel and wire。Liu Shihui,13,one of the two inventors from the Juvenile Activity Centre in Xuhui District,said they were hoping the machine could help ease the burden on bus companies who receive a lot of coins every day。“It can count 120 coins a minute and wrap 20 coins up at a time,”said Liu . Like Liu,more than 300 students from 14 countries and cities have got models or designs in the show。A team of students from Shanghai’s Xiang-ming High School brought to the exhibition 10 of their inventions。One of their inventions can wash pets。
