EVER imagined what it would be like to become ''invisible''? Students from Salesian English School made this dream come true with an excellent science project, which won them the first prize in the Proposal Competition of the 27th Joint School Science Exhibition (JSSE).
Inspired by the film Predator, the 18-year-old creator of the project, Arthur Wong Chun-Keung, said: ''We tried to utilise available technology to do something which had never been done before.
''We also wanted our project to focus on the theme of the exhibition - Dreams Become Reality. So we used the theory of light deflection to make part and even whole of the human body invisible.
''It is more like a delusion of eyesight or magic,'' said Chun-keung.
''One medium, be it a mirror or a light receiver, will deflect or absorb the light from an object. Then another medium will radiate the same colour and amount of light, making the object between them invisible,'' he explained.
''With amazing science projects of this sort, the annual JSSE has become not only an important event for schools but also for Hong Kong,'' said Professor Poon Chung-kwong, director of Hong Kong Polytechnic, at the opening ceremony.
As Hong Kong became more and more democratic politically, it was vital for locals to be more objective and open-minded, he said.
