One of the hottest viral videos of the last couple of days shows a man in a neoprene suit on a DIY waterslide, flying 115 feet and then landing safely in a kiddie pool. It’s accumulated more than 1.4 million views since it got uploaded to YouTube last week, and reactions were all over the place, ranging from dropped jaws to sheer amazement to a more cynical, “Nah, this can’t be real.”

And, after a bit of investigating, we’ve verified that it indeed wasn’t. The video was a carefully crafted viral ad for Microsoft’s Office suite Project 2007, and the production of the clip involved, among other things, a stuntman, a lot of editing, and a long piece of rope. Read on for more details about the campaign as well as an exclusive snippet of unedited video from the waterslide shoot.
