I can't believe there is an actual debate going on here. Even if this was possible, they would gradually start to lose buoyancy and slowly start sinking step after step but these guys fall in at a point where they've clearly reached the end of some submerged object. You don't go from 100% buoyant for 10 steps to 0% on the 11th. Come on guys... As someone mentioned before, you can actually see it disturbing the waster at some points. Fake.

No I didn't, I have no proof of it being fake...my statement saying it was fake was just my opinion by what I see, and I said there is a possibility of it being real, just I don't see it possible...which doesn't mean if I see it impossible that I am god and always right

There is so much more than water repelant shoes required for anything to come close to this act. http://www.societyofrobots.com/robot_jesus_lizard.shtml |

pretty funny that this is actually up for debate amongst users on this forum. the makers of the video even posted a blog entry titled:
"We got em!" for anyone who thinks this is actually possible, why don't you guys go try it yourselves and film it.

As the dude or the snow mobile is moving in a horizontal motion, they are experiencing gravity. That's what going to deviate their linear motion. As they travel across the water gravity will continue to pull them down. Since the snow mobile has higher momentum, the deviation will be less. The really really big factor that you have to take into account is the surface area and the lift effect (due to the motion of the wheels) If you look at a bike or a snowmobile they have a track or a wheel. these things comes into contact with the water in a certain way, they don't impart all of their energy in a downward motion, they impart their energy mostly in a horizontal direction, this acts to continue their speed, if they can maintain speed and as they speed over water their flat contact surface act as a surface to provide hydrollic lift. In the other hand, human has a stomping motion they impart their energy mostly in a vertical direction, they're mostly pushing down on water, very good motion for a surface with density, but poor motion for surface with low density. Did a physics problem like this before, I'll need to go over it again, it was a problem dealing with how much force one would need to impart to stay up, it was a calculation of the feet's surface area something with bulk modulus for the water and stuff, I don't remember, but he has to stomp the water at impossible speed. |

http://www.flickr.com/photos/bunnyfr...7623482301618/ Plenty of photos showing different animals walking on water. Its all about weight displacement. If you can spread out your weight evenly enough then you can float. Example, how can extremely heavy cruise liners float when they are 100s of thousands of tons? Weight displacement. I wouldnt call this stunt "walking" on water, its more like floating on water but you are moving forward .

this is ridiculous, there is far too much pressure on the sole of the foot to even come close to walking on water. and we don't come close to the speed required.
we would also have to displace an amount of water that is more than our weight for us to float. its simple physics guys. |
