Creating a 300-foot water slide down the middle of a public road sounds like a very American thing to do, but nope. Park and Slide is a crowdfunding project created by artist Luke Jerram that will turn Park Street in Bristol, England, into the coolest city in the world. That’s the goal at least; to shut down the street for a day, build the slide out of plastic sheeting and hay-bales, and open it up to the public—for free. The hills in this southwest England town are plentiful (they’ve been used for soapbox derbies before), so there should be no problem generating speed.
