On the 28th of April 2010, a video went viral showing off a new sport known as Liquid Mountaineering.
This clearly showed an ability to run across the surface of water, Given enough speed and sufficiently waterproof shoes.
The huge success gave way to many attempts at replicating the sport shown in the video.
A few people came close, but no-one ever got sufficient evidence to support it.
This will put it to rest once and for all.
