Slip 'N Slide is a children's toy invented by Robert Carrier and manufactured by Wham-O. It was first sold in 1961. The main form is a plastic sheet and a method of wetting it; when the surface is wet it becomes very slippery, thus allowing the user to slide along it. Some versions also include spray tubes on both sides and an inflatable swimming pool for the user to slide into at the end of the slide.
History
The creator was inspired by his son sliding on wet, painted concrete.[1] He used his job as an upholsterer to obtain a long strip of Naugahyde, sewed a tube to pass a hose into, and punctured the tube sporadically to allow water to spurt out. Carrier sold his invention to Wham-O where they replaced Naugahyde with plastic to reduce production costs.[2][3][4]
