Do not lament if you are too young to visit space with China's first astronaut Yang Liwei - there is lots of fun to be had on Earth. In the spirit of space adventure, a group of young children from Tuen Mun and Yuen Long entered a 'water rocket competition', organised by The Church of Christ in China Tam Lee Lai Fun Memorial Secondary School recently. The rockets were not powered by fuel, but air and water under high pressure. Students had to fill a bottle with some water, then pumped in air to create a high pressure. When a piston was released, the momentum was enough to launch the 'rocket' for more than a kilometre. The event included a workshop and a competition. It provided a chance for young kids to design and make their own rockets. Participants learned about science as well as the importance of teamwork. The organiser's aim was to arouse children's interest in technology. Buddhist Wing Yan Primary School (PM) won the best design award for their water rocket, while the projectile made by STFA Ho Yat Tung Primary School travelled the furthest. STFA Wu Siu Kui Memorial Primary School won the accurate landing category.
