The dome, a thirty-one great circle structure was made of aircraft tubing laced with cable which ran from the tubes through connectors at the joints. When the cable was tightened, the dome was erect; when relaxed, it collapsed into an easily-transported compact form. The prototype for the dome which Fuller brought with him had been constructed for a demonstration at the Pentagon in the winter. Assuming it would be erected indoors – it actually was erected in the Pentagon courtyard – Fuller had reduced the size to fourteen feet in diameter to accommodate an indoor space.

The project for the summer was construction of a double-walled, inflatable plastic skin cover for the dome.

The summer students erected the dome on a terrace at the end of the Studies Building. They demonstrated its strength by hanging by their hands from the structure and from a suspended platform on which a number of people could sit. Its light-weight was demonstrated by having three students lift it above their heads.
