Slip 'N Slide

Throwing yourself onto an obnoxiously yellow strip of plastic with (hopefully) just enough water to keep you slipping and sliding along—what could go wrong? If you're ever played on a Slip 'N Slide, you probably know already: Some people slid off the slide and onto concrete. Sometimes people didn't even make it that far, expecting a slip and a slide only to stop abruptly, resulting in some pretty serious spinal cord injuries.The CPSC didn't ban the Wham-O brand slides, which sold 9 million from 1961 to 1992 , but the organization advised that only children should use them. Sorry, teens and adults. You'll have to find another way to feel 8 years old again.
