The Science of Sand Sculpting
With 25 years experience sculpting sand, Mark explains the science of building sturdy castles. He throws out terms like "hydraulic compaction," the principle that allows tall and sturdy castles to stand strong.
He'll show your child how to use a bucket with a hole cut into the bottom, drawing up water into sand and letting it seep back down to make the grains stick together firmly.
Sandcastle building is best learned with hands-on play. Little ones will start with "pancake stacks" of sand and "volcano stacks"--soft mounds that allow carvers to make shapes in them. Mark will have 3 gallon buckets that kids can mix a slurry of Port A's particular type of sand and water once they dig to the water table on the beach. Then they can build castles--and anything else they can dream of.
