The artists adhere to strict rules during the contest. Each sculptor is given 10 tons of sand and are assigned an 18’ x 18’ square exhibit area. Work by the artists is limited to 24 hours in total length, which is spread out over several days. Forms for molding components are allowed and must be removed prior to the artworks being rated by the judges.
These are amazing every year. It's mind boggling that the artists only use sand and water to build these things.
Quick note: the "sponsor castle" seen above is not part of the contest and does not adhere to the rules previously listed.
