Glass may be the most popular construction material in the modern age, but constructing with glass is challenging and dangerous. We investigate the effect of nickel sulfide inclusion on glass. Then, machines gone rogue, London's Grenfell Tower, and a double crane that collapses at the Caracas subway construction.
