Pro skateboarders Clint Walker and Clive Dixon have lost their minds, and thankfully it makes for a great viral video. The two teamed up to build a full 360 degrees ramp Slip’N-Slide and actually made it work. The slide started on a roof and ended at the other end of the front yard. The team had to use a “combination of oil used as lubricant and a makeshift sling-shot connected to a pick-up truck tow-hitch.”
