Balloon artist Lily Tan and her team of 50 balloon artists used 79,854 balloons and spent 42 hours to construct a sculpture in the shape of a robot. Sentinel, as the robot was named, was displayed at Marina Square Shopping Mall from 16 to 18 Mar 2012. It measured 23.3m by 19m and 11.5m high and was accorded a Guinness record.
