When gravity and slick plastic aren’t enough, hook up a pulley and hit the gas. Outdoor outfitter Vooray built the slip and slide and 8-foot kicker on a private lake in Paradise, Utah. Director Devin Graham caught the action on video. He refused to hit the jump himself – he says three jumpers got knocked out cold while filming the summertime stunt. Some flew as far as 120 feet across the tiny high desert lake. The ATV driver, we assume, rode out unscathed.
