The Slip'N Slide is a toy manufactured by Wham-O, first introduced in 1961 after being invented by Robert Carrier. The toy is a long sheet of thin plastic, flanked lengthwise on one side by a heat-sealed tubular fold. The tube can be connected to any ordinary garden hose.

SLIP 'N SLIDE

The Slip 'n Slide was invented by Wham-O, one of the preeminent American toy companies, in 1961. Simply a rubber sheet that attaches to your garden hose and transforms into a lubricated sliding surface, it was a backyard fixture for decades until safety studies determined that it was responsible for a host of injuries—in adults. Kids are relatively safe on the Slip 'n Slide, but the increased weight of grown-ups makes them susceptible to permanent spinal cord injuries from sliding. Wham-O sent a recall notice for the Slip 'n Slide in 1993, recommending that adults and teens do not use it.
