THE steaming heat was the only match for the high-pitch activities on the Tang Siu Kin Victoria Technical School open day. The day marked the school's 60th anniversary. ''There are a lot more visitors this year because of the 60th year celebration,'' one student said. Primary students from two schools packed the covered playground. Many were drawn to the Music Club stall where they excitedly tried out the drum set and the xylophone. The glockenspiel especially fascinated the youngsters who squealed whenever they struck a strange sound. For those who preferred a quieter scene, Art Club members were ready to make sketches of them. Some students also produced instant bookmarks by sticking dry flowers on to blank cards which they gave visitors for free. An interesting stall was set up by the Yoga Club. The club was started only this year by a mathematics teacher, Mr Ko Wai-man. ''Yoga is an art that trains both the mind and the soul. I've noticed behavioural improvements in some students,'' Mr Ko said. Exhibits of a different nature were set up in the school hall. The Design and Technology section displayed a rich collection of students' works which included compact disc racks and 'Wok' ladles, etchings in metal, wood and plastic. One exceptional design was a shoes rack crafted by a fifth-former for the HKCEE. The rack, made of iron tubes, had electric sensors at the top that would emit air to dry shoes. When the shoes were dry, there would be a beeping noise. ''This model won much praise from examiners,'' said a student who illustrated how the gadget worked. The technical drawing corner featured some work samples and an expensive drafting table equipped with modern instruments to produce precise drawings. Chow Yim, a Form 4 student, made a flawless drawing of the school in perspective. ''It was not easy because you have to start all over again if you make a mistake,'' he said. The dressmaking displays gave the exhibition a feminine touch with lovely dresses, blouses, skirts, pants and even pyjamas. But the most attractive items were the hand-woven tapestries and shawls with landscape and figure designs. Biology students ventured into domestic science by making some yogurt, cheese, wine and oyster mushrooms. According to sixth-former Lu Man-hong, the mushrooms, which grew practically on scraps, promoted recycling. ''We spread some spawn culture on top of old newspapers and discarded cotton wool. The mushrooms popped up within three days under defused sunlight and a temperature of below 20 degrees,'' he said.
