How was the sculpture created and designed?
Anyone who has attempted to create their own art knows how difficult it is. Sure, you have a concept of how you want it to look, but when you put it down on paper, it never quite works out. Sand sculptures are a difficult endeavor that can take days to complete depending on the level of difficulty required.
Because professional sand sculptures are built with building sand, which is made out of sand, clay, and silt, they can stay for months on exhibit.
