THINKING OUT OF THE BOX It was a shoebox car with a difference. Four NUS Chemical Engineering students outshone their rivals in the 2001 Australasian Regional Chem-E-Car Competition by turning conventional wisdom on its head.

NUS car Designed to highlight the skills of chemical engineering students, the competition saw teams designing and building shoebox-sized cars powered solely by a chemical reaction to carry a load of 250 ml of water for 20 meters and come to a stop. Judging criteria were the successful completion of the task and the creativity of the car design.
Five teams (the others were two teams from University of Newcastle, and one each from University of New South Wales and University of Sydney) took part. The other teams used electrochemical cells to power their cars and make them run smoothly.
The NUS team dared to be different. They designed a gas-propelled car based on the decomposition of hydrogen peroxide. The rationale was that the gas produced would build up in the car's reactor. Opening a valve at a certain time would release the gas, propelling the car forward like a rocket.
Despite a failed first attempt, the NUS car went the farthest in its second run. It traveled 18.7 m, winning by a slim margin of about 50 cm against the Newcastle team's car.

They all are from chemical engineering department The winning team of Lorel Chow Li Ling, Warren Foo Shin Hwang, Yuen Hoi Yan and Zhu Ye Qing conceived this design while working on their Undergraduate Research Opportunities Program (UROP). Professor Lee Jim Yang was their supervisor for the project.
"Prof Lee suggested that we should have fun for our project and try to think of some innovative ideas. This is the reason why we chose to use gas propulsion," Hoi Yan explained.
