Elegance of design won judges' hearts at this year's Sony Creative Science Award (SCSA), a toy-making competition for primary school pupils. More than 4,200 toys from 96 primary schools were submitted this year, which is the 16th time that the competition has been held.

Ashutosh Menon Rajeev, 10, built a car that moves when a pendulum is swung. His creation won first place in the WhizKid category where participants had to make something that rocks, rolls, or wobbles.

The winner of the open category, Jacob Tseng, put together a contraption from magnets, rubber tubes, and bicycle spokes. The Primary 3 pupil's toy features a magnetic elevator that lifts a ball to the top of the device and lets it fall in an infinite loop. "I built the toy in one week," said the 9-year-old. "I was really rushing, because I had to get all the materials."

Speaking at the award ceremony, Speaker of Parliament Madam Halimah Yacob praised the SCSA for giving pupils the opportunity to translate ideas into action. "The process of toy making captures a child's imagination, and forms the discovery process which is an important learning tool for our young children," she said.
