The video shows a group of people in scuba gear underwater carving pumpkins. The pumpkins are placed on the sandy ocean floor, and the divers are using various tools to carve them. The pumpkins have different faces drawn on them, and the divers are carefully carving out the designs. The water is clear, and the pumpkins are bright orange, contrasting with the blue of the ocean. The divers are wearing black wetsuits and are using small knives to carve the pumpkins. The video captures the unique and creative way of celebrating Halloween underwater.
