Playground slides are found in parks, schools, playgrounds and backyards. The slide is an example of the simple machine known as the inclined plane, which makes moving objects up and down easier, or in this case more fun. The slide may be flat, or half cylindrical or tubular to prevent falls. Slides are usually constructed of plastic or metal and they have a smooth surface that is either straight or wavy. The user, typically a child, climbs to the top of the slide via a ladder or stairs and sits down on the top of the slide and slides down the chute. In Australia, the playground slide is known as a slide, slippery slide, slipper slide or slippery dip depending on the region. Sliding pond or sliding pon is a term used in the New York City area, whereas sliding board is used in the Philadelphia area and other parts of the Mid-Atlantic.
History
The earliest known playground slide was erected in the playground of Washington DC's "Neighborhood House" sometime between the establishment of the "Neighborhood House" in early 1902 and the publication of an image of the slide on August 1, 1903 in Evening Star The first bamboo slide at Coney Island opened for business in May 1903, so it is unclear which slide was first the playground slide or the amusement park slide. Early slides were frequently referred to as "Slide, Kelly, Slide", "Helter Skelter", or "Shoot the Chutes". The manufacturer, Wicksteed, claim that the playground slide was invented by founder, Charles Wicksteed, and installed in Wicksteed Park in 1922, The discovery of Wicksteed's oldest slide was announced by the company in 2013. However, this has been countered by a 1916-07-25 US Patent and others who refer to a roof-top slide in NYC around 1900, the nursery slide of the young Tsar Alexei, at Alexander Palace in Tsarkoye Selo built around 1910, the 45-foot slide at the Smith Memorial Playground in Philadelphia, which was installed in 1904, or the Coney Island Slide around 1905. Indeed, Arthur Leyland's book "Playground Technique and Playcraft", volume 1, originally published in 1909 and revised in 1913, gives full instructions for the construction of a metal playground slide.
A spiral slide is a playground slide that is wrapped around a central pole to form a descending spiral forming a simple helter skelter.
A wavy slide is a slide that has waves in its shape, causing the person sliding to go up and down slightly while descending.
A tube slide is simply a slide in the form of a tube. It can also curve or have bumps.
A straight slide is a flat slide that just goes down at a slight angle.
Amusement-park slides are just larger versions of the playground slide, much higher and with multiple parallel slideways. Participants may be provided with a sack to sit on to reduce friction for higher speeds and to protect clothing.
Drop slides are slides with a vertical or nearly vertical drop.
Water slides are a type of slide that water goes down to create a slippery slide; found near water, generally in water parks or pools.
There are several other different types and styles of slides. Slides can also be sub-classified as either free-standing slides, slides that stand on their own, or composite slides, which are slides that are connected to another or several pieces of playground equipment.
Safety
Playground slides are associated with several types of injury. The most obvious is that when a slide is not enclosed and is elevated above the playground surface, then users may fall off and incur bumps, bruises, sprains, broken bones, or traumatic head injuries. Some materials, such as metal, may become very hot during warm, sunny weather. Plastic slides can also be vulnerable to melting by arson. Some efforts to keep children safe on slides may do more harm than good. Rather than letting young children play on slides by themselves, some parents seat the children on the adult's lap and go down the slide together. If the child's shoe catches on the edge of the slide, however, this arrangement frequently results in the child's leg being broken. If the child had been permitted to use the slide independently, then this injury would not happen, because when the shoe caught, the child would have stopped sliding rather than being propelled down the slide by the adult's weight.
