Swing In The Underground, San Francisco, United States

• Tire swings are a form of swing made from a whole tire. These are often simply a new or used tire hanging from a tree on a rope. On commercially developed playground swingsets, oversized new tires are often reinforced with a circular metal bar to improve safety and are hung on chains from metal or wooden beams. They may hang vertically or hang flat, suspended from three of more points on one side. These flat type of swings can hold three or more children. Pumping is achieved by using one or two of the three chains attached to the swing, and two (or more) children can pump in turn. Tire swings can also be used in spinners, where the occupants use their feet to propel the tire. Children find ways of performing dangerous stunts on tire swings, and because of this, many have been removed from schools and parks.
Natural swings may be created by lianas (creeper plant) in a subtropical wild forest like Aokigahara forest near Mount Fuji.
• A rope swing is a swing created by tying one end of a length of rope to a tree branch, bridge, or other elevated structure. A knot or loop is usually put on the other end to prevent fraying and help the swinger stay on. Rope swings are often situated so that those swinging on them can let go and land in water deep enough to cushion the fall and to be swum around in. Many other dangerous/unusual stunts can be done using 1 or more rope swings. This is the most dangerous type of swing.
The incorporation of a short board such as a skateboard in which the rider stands is called swing boarding. It is made safer by the use of an attached board and a harness for the rider.
