Shrieks of delight rang out at Tung Chung yesterday as children enjoyed a mobile water playground. The Play Mobile truck rolled up to Yat Tung Estate mall, providing games for more than 300 children. The fun included a slide with a paddling pool and a pool filled with pipes and balls for children to learn about the properties of water under the guidance of five instructors. The programme, the first of its kind in Hong Kong, was set up by Playright Children's Play Association and is sponsored by Zurich Insurance. The Home Affairs Department provides the space in areas with many children but few play facilities, such as Tung Chung, Tin Shui Wai, Sheung Shui and Tseung Kwan O. The concept was not new, said Anton Wan Nam-sing, the group's play development manager, saying it was common in Europe, with Germany having several dozen such mobile play trucks. Japan also provided play facilitators in playgrounds. For more information, call Playright at 2898 2922, or visit its website at www.playright.org.hk .
