Guys, I have stumbled upon this incredible video - I honestly wish it was real, but somehow, SOMEHOW, it seems to me that it's only a commercial/ viral vid for these shoes



What do you think?

Mythbuster explanation.

SPOILERYes it is a viral ad. SPOILERBut still a cool video.

Yeah, Korbliz has beaten me to it but here's the company themselves talking about it

The good old question: Could Jesus really walk on water, is it even possible?

Well it's unknown if he did, but yes, it's entirely possible.
There's over 1,200 creatures which still do walk on water today.

The tiniest creatures are gliders. Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together. Larger creatures are slappers. Surface tension forces are too weak to support the weight of a larger body.

The basilisk lizard, for instance, can dash at speeds of more than five feet per second by slapping the water with its hind feet. Its downward stroke pushes water away from its leg, creating a tiny air pocket around its foot, against which it pushes off.



So what about some larger creatures? There are even some tail-walking dolphins which strike across the surface of the water with enough force and speed to keep their heavier bodies from going under.



It would even be possible for a human. I wouldn't call it myth busted just yet.

Well the Liquid Mountaineering myth is definitely busted but as for the walking on water thing, I like to think that anything's possible.. I don't know enough about physics to prove or disprove but the human mind has proven many times it's capable of acts beyond our preconceptions.. who knows ? It's a nice thought

It would be an extremely nice dream, the likes of flying, for me at least I was dreaming about flight since early childhood!

I'm so disappointed. I wanted it to be real.

Posted by: Gabriel Leopardi Aug 31 2012, 02:37 PM

The first video looks so real, and I was starting to believe that it was possible but then I was the myth buster and I felt very disappointed!!

Posted by: Cosmin Lupu Sep 2 2012, 08:12 PM

Guys....I felt in the exact same way... I WANTED IT TO BE REAL - I WANTED THOSE SHOES! But hey, then again, that's EXACTLY WHAT THE SHOE MAKER INTENDED

This is a GREAT example of a great AD

Posted by: Ben Higgins Sep 2 2012, 08:31 PM

You can still buy the shoes though !!

Posted by: Cosmin Lupu Sep 2 2012, 08:35 PM

I honestly don't like the design But if they could've performed the trick, I would've closed my eyes OR ask them for a nicer model to fit my tastes

Sorry guys, this is not possible

Water has a surface tension of 72 dynes per cm at 25 celcius degrees. This is quite unnatural units, it converts to 0.072 Newtons per meter. So this means in order to break a surface film of water of 1 meter long you would need 0.072 Newtons of force. Say a human foot is about 25 centimeters long. Then you would need 0.018 Newtons of force to break a surface film of water of 25 centimeters. Now an average human weighs say anywhere between 60-80 kgs. Roughly our weight on Earth is 600 - 800 Newtons. Suppose you want to stand on water on two feet, then your weight will be divided in equal parts for both feet (of roughly 25 cms long) which is 300 - 400 Newtons. You see that 300-400 Newtons is so much larger than 0.018 Newtons, which was enough to break a surface film of water of 25 centimeters long... So yea , it is not quite possible

Why did you have to ruin my dreams in such an irreparable way, Mert?

Posted by: Opetholic Sep 2 2012, 09:04 PM

Sorry

Posted by: Ben Higgins Sep 2 2012, 10:03 PM

Yeah, he's gotta seriously make up for it now by submitting some awesome guitar videos !!

Posted by: Cosmin Lupu Sep 3 2012, 07:12 AM

Indeed he does! Featuring bending and vibrato!

Posted by: Ben Higgins Sep 3 2012, 08:47 AM

Yes ! The 2 most annoying techniques that nobody wants to work on !!

Posted by: Opetholic Sep 3 2012, 08:45 PM

Ummmm I am at the moment stuck with some string skipping I am not able to skip that exercise I learned another bar of it today with this tempo, I think I will start with bending and stuff maybe in ummmm 10 years..

Posted by: Alex Feather Sep 4 2012, 02:40 AM

It looked so real! Disappointed I was about to go to the ocean to try it out!

Posted by: Cosmin Lupu Sep 4 2012, 01:53 PM

I think that doing the skipping stone trick on the face of the sea or ocean is way more difficult than on a still water

Alright! Let's see you win the heart of a girl with string skipping

Posted by: Opetholic Sep 4 2012, 06:13 PM

Hmmm, it is not the heart of the girl I want to conquer, it is her string so you see, string skipping can be a very useful skill

Posted by: Cosmin Lupu Sep 5 2012, 07:44 AM

Got me on that one

Well, here's something that's definitely NOT fake... This is another childhood dream for me - flying without any man made flying device...

Posted by: Ben Higgins Sep 5 2012, 09:14 AM

That takes some serious courage !!

Posted by: Cosmin Lupu Sep 6 2012, 08:27 AM

But it is flying without any apparatus man ... just look at it...

Posted by: Ben Higgins Sep 6 2012, 10:12 AM

I know... it's bonkers but brilliant !

Posted by: Cosmin Lupu Sep 6 2012, 10:24 AM

I don't know if in this vid you can see the dude flying through that hole in the rock - that's JUST INSANE..

Posted by: SirJamsalot Sep 10 2012, 06:46 AM

I'm really glad they didn't show the bloopers ~ I don't think I could stomach it. They also didn't show the landings... ug.

Posted by: Cosmin Lupu Sep 10 2012, 06:49 AM

There's a vid on YT shot by Discovery, showing what happened with a crew of wingsuit dudes in mid air - if it's made by Discovery, most likely that it's not gruesome but I didn't want to watch anyway
