Soon they heard the sea.They were carrying the usual rope(绳子),and it was hanging down from the basket of the balloon.At the end of the rope they had tied a metal box.This could hold water,or it could be empty.So they were able to change its weight(重量).It was for use over the sea.They were also carrying some bags of sand.
