VIDEO: Thrill-seekers make DIY waterslide - off 50-foot cliff

In America they have these things called 'slip-n-slides', and this one's pretty awesome (in Ireland, we have paddling pools).

Well, this looks like fun…

A group of US adrenaline junkies have an online hit on their hands after setting up a giant slip-n-slide (you know, those homemade plastic waterslides that you get all soapy and wet so they're slippy enough to… um, slide on) to propel them off a 50-foot cliff and into the waters of Lake Powell, Utah.
