World champion sport stacking athlete Jeanie Fung's skills are just a blur. Her hands move so fast as she stacks and unstacks cups in sequence that it seems as if you are watching a film that's speeded up. But you're not.
Hongkonger Jeanie, 15, is officially the fastest female in the event after winning the overall title at this year's world championships in Butzbach, in Germany. She won three silver medals in her age group's mixed-gender categories, but was also crowned overall women's champion thanks to a combined time of only 9.756seconds for the tournament's three events - making her the world's fastest women's sports stacker.
The Year 10 student at West Island School took an interest in the sport after she saw a set of cups displayed in a toy shop while on a family holiday in Japan about four years ago. 'I'd never seen such toys in Hong Kong before,' says Jeanie.
'I couldn't read the Japanese words printed on the box, but took away a leaflet in English so I could read it.'
She researched the sport - looking up the English word 'stacking' online and watching short films on YouTube of competitors stacking cups as fast as they could. 'It helped me get the basic idea and I really wanted to try,' she says.
The sport - also called cup stacking and speed stacking - originated in the United States in 1990 and has more than 400,000 regular participants worldwide.
