In the PolyU Summer Programme 2021 on 3 Aug 2021, about 50 participants from different secondary schools joined our interactive workshop – Plastic Bridge Challenge, which involves design, fabrication and testing of a bridge structure. They were given one hour to build bridge in groups of five with plastic sticks only. Each bridge structure had to support loads successively added until collapsed. The winning groups were those who produced structures with the highest strength to weight ratio.
