If you're determined to go out and try to be Jesus, just remember to take a towel, you'll need it. 

Great video though, best fake I've seen in a while.

damn this vid is exploding on the internet. anyway, a lot of people think it's a viral marketing video for "Hi-tec".. the clothing company they are all wearing. Just look at all their hats, jackets, and shoes, all Hi-tec. I don't know what I think, I'd like to think it's real, but there's no way of knowing

When you try this, PLEASE make sure you video it, and post your failure for us all to see.


Tell me, umm, exactly why would the TOPS of the shoes need to be water repellant, to be able to "walk on water"? The rubber soles on all our shoes are completely water repellant. (That would be the part that hits the water while you are "running" on it.)

Look up these concepts: Surface tension. Weight distribution. Displacement. Angle of attack.


I will say, though, they did a great job. It was very entertaining.

Or unless you have a basic understanding of how water's surface tension works.  http://en.wikipedia.org/wiki/Surface_tension  Simply put, unless you're a super light lizard with webbed feet, it's going to be really hard to pull it off.  Don't take my word for it though, go try.  Just remember the towel.

This is probably fake, unless you can run 70 mph and have webbed feet and weigh 4 oz. then you're not going to be able to do this. Look at it, see how they all fall at the exact same place, its probably a sunken boat dock or a couple weighted boxes.

I want to believe this is true, but the laws of physics say no.
Title: Re: OMG holy hell This is next level
Post by: Will Ahlberg on May 08, 2010, 02:19:04 PM
i dont believe it and this is why:

Number one: There are 2 spots that he ALWAYS falls off at. a spot like 10 feet out and a spot like 30 feet out.

Number two: When you look at his feet, they arent like slowly sinking or gliding. He is pushing down and there is a sudden stop at his feet. You can see this easier when the vid is in slow motion.

Number three: People do fake vids that look amazingly real all the time. its called technology.

Number four: It goes against every law of physics there is lol.

While this is a really cool vid, i dont think its real.

what about that lizard that runs on water, if it can do it why can't we?

Because he weighs 3 oz., has webbed feet, and can run a 4 ft. per second and create air pockets beneath its feet.   :P

I want to believe this is possible to some degree so hard. I'm definitely going to give it a go once the water warms up in my area. Their stuff is likely BS on getting like 10 "steps" but if I can even get only a small few like 3 it would be good enough for me.

The thing that really makes it fake for me more than anything else is their complete lack of explaining the technique of how do to this stuff. I think if you are starting a new sport/movement it would make sense that you at least explain the basics of how to perform it.

simple physics.

the ability for us to run on land requires a normal force from the earth to push back on us. thus allowing us to press our legs against the ground and move forward. that creates a pressure between our feet and the ground.

water is non-compressable. simple fact. you just cant compress water. no matter how fast our little stick legs slam onto the the surface of the water without running like 70 mph or being like 150 lbs lighter, its is impossible.

boats dont compress water, they have air pockets that allow them to float on top of the water. it was a cute vid tho. sweet lookin shoes.
Title: Re: OMG holy hell This is next level
Post by: Ryan on May 11, 2010, 09:25:07 AM
Air pockets do not keep a boat floating, you can make boats out of whatever, including concrete.  What keeps a boat floating is the shape of the boat, and the total density of the boat verses the density of the water.

You are both wrong, although density does play a part. What keeps a boat floating, is that it DISPLACES enough water to weigh more than what the boat weighs. The shape means nothing for the floating part, only for how efficiently it 'moves' through the water. A boat of concrete that weights 1000 lbs, has to displace > 1000 lbs of water, or it will sink. A boat floating on saltwater will have to displace fewer gallons than one floating on freshwater, as saltwater is denser, and therefore weighs more per gallon.

You, at, say 150 lbs, must displace at least 150 lbs of water for you to float. Which you do, but only barely. That's why you float just under the surface of the water.

Thank you, for being the only person here who knows some basic physics. I was about to explode until I saw your post.


To make this concept work, a person would have to find a way to displace an amount of water, with a single step, about equal with their bodyweight. Considering the size of our feet versus our body mass, that's not possible. Of course, as speed is added, then it becomes more possible. The faster you throw a flat rock, the more skips it does. So, you would need some kind of constant velocity that would exceed the weight to water displacement ratio. And its more than we are capable of running.

I mean, lets think about barefoot wakeboarding. Some brief research on the internet tells me that an average weighted barefoot skier needs to be traveling 25mph for any kind of flotation.

So you need to achieve and sustain at least 25mph in order to travel on water in any manner other than a swift dunk.

Fun facts for the win.

But I love the creativity of this video.

At that point, however, you aren't actually "floating", you are "skimming". That is where the laws of physics for displacement are overridden by those dealing with surface tension. The water's surface acts like a barrier, because the angle at which your feet meet it is very low, due to your speed.

Did you know the atmosphere also has it's own surface tension, and if a spacecraft were to approach the earth at too flat of an angle, it would deflect or "skip" off into space, just like a stone off of water?

No, that deals with the movement of fluids/gasses. Displacement is under Archimedes' Principle.

Google is your friend. I had to look up which principle it was myself, as it has been over 2 decades since I've had any science classes. But I enjoyed physics, so I remember what the principles are, just not the names. LOL

This is true. I guess that's where the whole wakeboarding thing has to come into play, since that's definitely skimming.

Oh god this is killing me how many people are falling for this.

This is officially  a fake its a viral marketing add for Hi-tec gear. Get over it.

Its easy to tell its fake because first of all it is impossible, their clearly running on plexiglass ramps, and the interviews are obviously canned its intended as comedy.

Read up on the physicals of surface tension and how species that do run on water like Basilisk lizards do it its pretty easy to figure out why this is impossible.

Oh, the irony.  ::)


Btw I just did my research and found what I was looking for without clicking a single link. "... Liquid Mountaineering is a new term created by some European pranksters to describe a new technique they've pioneered for walking on water."

Sorry I didn't bother looking into before, simply because I'm not all that gullible, people have been using this technique for movies and all kinds of stuff for a long time. Everything about that video is obviously fake, from the way the waves are moving to the sudden drop to the normal one or two steps after they reach the end to the simple and obvious fact: IT'S FREAKING PHYSICALLY IMPOSSIBLE!

Sigh, no wonder people make fun of us Americans so much.....

Quite a laugh watching that video. The guy who came up with the name "liquid mountaineering" is a genus  ;D I still want to try it however, just because it would be really funny to run really fast into the water and sink right in

Just make sure to bring a camera  ;D
