The next challenge was to make a Singapore flag made up of 8500 drink cans, in tandem with the National Day celebrations that were around the corner. For this round, Fuhua was teamed up with Townsville Primary School and competed against Hwa Chong Institution and Innova Primary School. This round was very intensive, with students having to first gather at least 8500. They eventually gathered more than 10,000 cans. Much time was spent washing and painting these cans and many different models of stacking them were tried before settling on the version used for the actual challenge. In the end Fuhua and Townsville won by 10 marks (86 to 76), and Fuhua got into the Grand final, with the subsequent challenge to break a world record.
