LONDON—This 22m high rocket was built out of junk and had smoke coming out of its windows. It stood in the Roundhouse, London, a former industrial train turning station that has since become a permanent performance space. I turned it back to industrial use by creating a live rocket factory, much like NASA’s barn at the Kennedy Space Center in Florida. The materials took five months to source from various scrap yards in England. Most of it is made from steel or fiberglass, plus a few tractor tires and several industrial fans. The bottom part is a discarded tank from a toothpaste factory
