You can't run on water. You just can't.
But you can - with the right technique, a concentrated will and the help of very thin plywood - do something almost similar.
Shi Liliang, a Shaolin monk from Quanzhou Shaolin Temple, recently ran for 120 metres across a lake by stepping very, very quickly between 1cm-thick boards of light wood.
The video above is crazy but it doesn't break any laws of physics. Kotaku reports he's going for 150 metres next.
