This display demonstrated how an arch is constructed using gravity to put enough pressure on each block. No mortar or glue is required. Each block is numbered and the starting spot is marked.
But it takes a team to hold the partly constructed sides and gather the correct blocks in sequence until the capstone is put in at the top. Here everyone is doing their bit.
