VietNamNet Bridge – Seeing plastic bottles floating at sea, Nguyen Thi Quynh Tram and her two friends at Binh My Primary School in HCM City’s coastal district of Can Gio got the idea of using them to make a life jacket, and it won them the first prize in a contest called Sang Kien Cong Dong 2017 (Social Ideas).

Tram, 11, said: “Once I and my friends wrote our wish on a paper, put it into an empty plastic bottle and threw it into the sea. When we saw the bottle floating, we thought we could make life jackets from them.”

Many of her schoolmates from the rural hamlet of My Khanh come to school by boat through canals without life jackets, she said, explaining they are too poor to buy them.

The boat owners do not provide passengers with life jackets either.

Tram and her friends put together five 1.5-litre bottles using nylon and polyester lines. To strap them on, they used straps from discarded life jackets.

The cost is not high, and their schoolmates can afford them, they said.

Truong Thanh Tri, a computer teacher at the Binh My Primary School who helped them make the life jackets, said: “I have tried it. It is safe for students to use.”

These life jackets would help reduce drowning deaths, and reusing plastic bottles is a way to teach the students how to protect the environment, he said.

He plans to make a do-it-yourself booklet on how to make them for the benefit of other students.

Second prizes in the contest went to Trinh Thi Minh Huong, a literature teacher at Phu Nhuan High School who uses games to make literature lessons more interesting, and two girl students at Le Hong Phong School for Gifted Students who developed a watch with four sensors that warn the wearer against epilepsy seizures. 

There were seven other awards for individuals and teams for creative and innovative practical ideas.

The awards ceremony was held yesterday in the city.

The contest was organised by the city Department of Science and Technology’s management division for science and technology research at grassroots levels in co-operation with Kham Pha (Discovery) Magazine.

Nguyen Viet Dung, head of the department, said the contest encourages every one to come up with creative ideas which could change people’s lives for the better and contribute to the city’s socio-economic development.
