Title: Walk on water... fake?

So?

Fake, or should we all run and buy water repellent shoes? ;)

I am not a physicist or anything but I'm pretty damn sure that's fake.

I mean, my feet don't absorb water.. That doesn't mean I can run on water :P

It's pretty non fake to me. The pattern in which he does that run, seems very believable to be fake.

It's as easy as building a ramp and placing it just under the water surface so it is not seen from the camera's angle.

The YT comments are pretty interesting.

I'd like to believe in such a thing, but I'm too skeptical, until I try it myself! ;D

Really though, while it's obvious how it could be done with the ramp under the water, still they seemed pretty convincing, plus they (he) fell into various places at various times. Probably jumped off the ramp, but either way... An interesting idea, never the less.

And of course there's also this: http://www.welcometointernet.org/Jesus%20Cat.swf Which seems much less fake, because of the cat.

Really dunno what to think of it. It's fun though, isn't it?

Indeed. It's lacking vital evidence, like, someone else just standing in the water so we can get a real idea of the depth, and stuff. Still - fun to watch!

It reminded me of this: http://www.youtube.com/watch?v=J6bSG9OWZDI&feature=related

The water part starts at 03:15

When the guy is talking about the "technique" around 1:10, there is a slow motion close up which shows nicely that the guy's feet get submerged to his ankles, which shows that it's not about surface tension (they're saying that it's about skimming).

Also, two minutes in, when they show the run in it's full lenght, you can see a dark spot just under where he runs ending where he falls.

I believe it's doable in water with very high salt concentration.
There's very few lakes like this though.

I'm pretty sure you can kind of see something under the water...

And anyway, you can see the mud where they've worn away the grass where they run from... why would they all do it from EXACTLY the same place and run in exactly the same direction each time unless they were running on some kind of structure.

Take a look at the run at 2.22...you can clearly see how he's trampling on something just underneath the surface - every step is the same depth - and then suddenly the ramp ends so he falls down very abruptly. Why would one step be "floating" and the very next, with equal momentum, make him plunge deep into the water?

And what about the jet ski trick? What is that all about? Would he pick up more speed by being dragged the first couple of meters by a jet-ski? IT DOESN'T MAKE ANY SENSE

PS:
Here's diva Chris Angel doing the same thing, although he's mastered it to a degree where he doesn't even have to run.

Yes, I thought the point about retarded fags was quite thought-provoking.

To me it's very obviously fake.  The physics are way off and you can see the water breaking/flowing differently where there is some platform just under the surface.  It's a pretty good effect I'll admit, but still looks fake to me.

Plus the way they are talking about it just feels ... forced.  It, again, just misses feeling real to me.  All in all I'll give this a 7/10 for being convincing, but not believable.

It couldn't be possible at all, so of course it's fake. Looks funny though.

And yes, what they're talking feels forced indeed.

I love how they act as though water-resistant shoes are some revolutionary invention... when the sole of all shoes is rubber, and thus waterproof anyway.

So in a sense these boots should hold you up better seeing as how they're rubber and also create a bubble inside them that'll help you float.

Personally, I'm totally convinced.

I mean it was all really sciencey, ya know.

and if his shoes are water resistant and he puts them on water then they must go up, right?

Simple physics If you think about it.

The fact they repell water doesn't automatically mean they can support a whole human weight, taking the water density into consideration. IF it was possible, I doubt it would be because of the shoes.

Does the fact that when you breathe in you float doing nothing mean that it's sufficient to breathe in to walk on water?

Thats only because you breathe into your *lungs* which are in your head or near your stomach or something.

If someone could find a way to breathe into their feet I'm sure it would be possible.

If you trace this water-walker's lineage back you'll discover that he is, in fact, a distant relative of Jesus.

However, given a small genetic hiccup in the late 13th century (it's a long story) he didn't fully inherit the walk-on-water gene thus he must achieve speed and can only maintain it for a few steps before science takes over.

He is well aware of his lineage however, given the recent treatment of those claiming to be the "messiah" (Jim Jones, David Koresh, Marshall Applewhite, etc) and his background in marketing, he decided the better route was to capitalize off his heritage by producing a line of shoes and duping the willing and gullible into buying them.

Brilliant if you ask me.

I once floated in mid-air through sheer force of will (and leg muscles). I first lifted one leg up in the air, then the other.
Simple.

Didn't mythbusters have an episode for water walking? As far as I remember, they ended up walking on corn syrup.

Yes, I think a video of that is actually in the related videos section!

Guys. Seriously.

The average male has way too much surface pressure on both feet to be able to do this. Even on a non-Newtonian fluid, go slow enough and you'll sink.

No way in hell this is real. It's YouTube. And it's 2010. Come on now.

Just saying "the average male"  implies that there are outliers who could perhaps achieve this. 

One of my engineering courses in university focused on surface tension and we calculated the ratio of an animal's foot area to its mass required to walk on water.  I don't remember the number but it was ridiculously large.   I think the Mythbuster's episode mentioned explored this and even with an appropriatedly sized pair of foot extensions they still couldn't achieve this because the foot would have to make contact with the water surface in a perfectly level manner.

The video posted is amusing though. Their pseudo-scientific explainations were delivered with an Owen Wilson-like deadpan that made me think they wanted to viewers to be in on the joke.
