CONCEPT
Fiske Planetarium had been using a piece of stretchy fabric clipped to the outside of a hula-hoop to demonstrate how gravity warps space.
I was tasked to create a larger demo that was self-supporting, could be quickly set up and taken down and transported in a similar form factor to the hula hoop version.
The result was made from a couple dollars worth of parts and collapses down to the same form factor as the original!
