Below: mini ducks in Ngong Ping and Florentijn Hofman with the reinflated second duck. "I thought it was a common rubber duck. The deflated duck was spotted being reinflated in the shipyard with its tail attached to a crane. University of Hong Kong chemistry professor Fung Ying-sing said higher temperatures will result in higher pressure on the duck, affecting its structure. Some 1,000 of the mini ducks will be sold at Ngong Ping Village today with profits to be donated to the council.
