Choose a spot near wet sand, above the tide line
Gather sand, water, a bucket, and a shovel
Pack wet sand tightly into the bucket
Flip the bucket upside down and lift it off carefully
Build a base with several packed sand mounds
Stack smaller packed mounds on top to form towers
Smooth and shape the walls with your hands
Carve doors, windows, and details with a stick or shell
Add wet sand to repair cracks and strengthen weak spots
Decorate the castle with shells, sticks, and seaweed
Keep adding water to maintain the sand’s firmness
Finish before the tide reaches your castle
