slide
Slides, especially playground slides, are playground equipment installed in playgrounds, parks, schools, and so on. The cross section of the slope of the slide may be flat, rounded in half, or cylindrical. The reason why the cylinder is cut in half or cylindrical is to prevent the children from falling. The slides are made of plastic or metal, but they are straight or straight. Children using slides go up the top of the slide through stairs or ladders, then slip down the slides.
