Today is your last chance to go to an exhibition featuring innovative projects by local and foreign students, including a three-dimensional (3-D) device, music gloves and a rotating teahouse.

The 38th Joint School Science Exhibition (JSSE) is being held at the Central Library in Causeway Bay.

Under the theme 'Fantasy-Amusement in Science', students from 28 local secondary schools and five universities, along with their counterparts from Kuwait, South Africa, China and Taiwan, came up with creative ideas which can bring happiness to people.

Although they are just concepts at present, a panel of judges who evaluated the projects said they could become reality one day.

At the opening ceremony last Friday, Secretary for Environment, Transport and Works Sarah Liao Sau-tung encouraged students to take science seriously.

'Science is an interesting and rewarding career. You turn your dreams into reality through dedication, imagination and innovation,' said Dr Liao, who was on the JSSE preparatory committee in 1968 and 1969.

'Louis Pasteur [a great 19th century biologist] said: 'Luck favours the prepared mind.' You should put in more effort and take your science seriously.'

The local secondary school teams booked their place in the exhibition after their proposals were accepted by the judges.

The top three prizes went to St Paul's College, Tai Po Sam Yuk Secondary School and St Francis Xavier College, respectively.

St Paul's also took the best Web design award. Their winning project, Free-Dimensionalism, comprises a set of devices which takes 3-D pictures without distorting their colours.

The team - Keith Wan Hay-man, Wong Ka-chun, Kong Kin-lok and Kelvin Cheung Quan-hang - made use of concepts such as vectograph and polarisation of light in their design.

The liquid crystal device (LCD) was also used.

Their first product was a stereoscopic lens that produces a 3-D image which can be mounted onto any camera, including digital video cameras. The user has to wear a pair of special, coloured spectacles to see the pictures.

They also created a stereoscopic magic box which, when used with appropriate equipment, can convert a two-dimensional image into a 3-D one.

Sam Yuk came second with a pair of gloves which allow users to play music anytime, anywhere, by simply moving their fingers.

The device can also help people to learn the staves. Each button on the gloves produces a specific note.

St Francis' innovative teahouse rotates at a constant speed. With its special facilities, such as a canopy, reclining seats and music, the team believes The Rotating Garden can provide a high standard of entertainment as well as a relaxing atmosphere for the public.

Organised by the JSSE in association with the Leisure and Cultural Services Department and the Hong Kong Science Museum, the exhibition will close at 4pm today. Electronic goods manufacturer Philips is the chief sponsor of the five-day event.
