Travellers to the airport might well have wondered if the Ma Wan Channel had been turned into a giant tub - the 16.5-metre-tall Rubber Duck, created by Dutch conceptual artist Florentjin Hofman, was towed by a tugboat - less than half its size - around Hong Kong yesterday. It passed dozens of vessels and went under the Ting Kau Bridge, catching the eye of coastal residents, ship workers and many online users. The duck will be moved to Harbour City in Tsim Sha Tsui next week.
