5. The Perisphere Appeared to Float

The design for the Perisphere called for eight relatively small pylons​ for support, but they were to be hidden to give the illusion that the orb was floating. This was accomplished by strategically placed fountains and covering the supports with mirrors. At first, the fountains didn’t provide enough coverage, but their pressure was increased and more were added to create the desired effect.
