Abstract: A balloon sculpturing device includes a weight unit and a plurality of sculpturing rings. The weight unit includes a weight member and a long cord member having a first end connected to the weight member. Each of the sculpturing rings includes a cylindrical body, which has a first and a second open end and is formed with a plurality of longitudinally extended and circumferentially spaced slots. At each of the slots, a balloon can be mounted and held to the sculpturing ring. A second end of the cord member is sequentially extended through the sculpturing rings having balloons mounted thereon, so that all the balloons are combined into a decorative arrangement.
