This demonstration video, for use in a primary school technology classroom, shows how strong structures can be made using triangular shapes. It then proceeds to challenge learners to make a tower from 20cm straws or other material of similar lengths. The tower needs to be able to hold a tennis ball (or object of a similar size and mass) 30cm above a surface.
