Sand Sculpture

A variant on the sandcastle is the drip castle, made by mixing the sand with water and dripping it from a fist held above. Some refer to the technique as "dribbling." When the slurry of sand and water lands on existing sand structures, the effect is Gaudi-esque.
Festivals and competitions
Since 1989, a World Championship in Sand Sculpture has been held in Harrison Hot Springs in Harrison, British Columbia, Canada, also known as "Harrisand". The competition has solo, double and team categories. The world's tallest sandcastle was built on Myrtle Beach in South Carolina as part of the 2007 Sun Fun Festival. The structure was 49.55 feet (15.1 m) high. It took 10 days to construct, and used 300 truckloads of sand.
