Mind = BLOWN: Static Flow of Water [Video]

Creating the illusion of a static flow of water using sound. Of course this isn’t my idea and plenty more refined examples already exist.

So, anyone out there who can explain how this illusion was created? Let us know in the comments section below!

    • No I don't think so. The drops would be blurred during the finite time it takes the CCD to capture an image (though the focus of the video suggests a wide aperture with shallow DOF letting in lots of light). A strobe would work but it would show up obviously in the video. With such a seemingly simple setup I'll be convinced when I see many more of these made by other people. It's a real effect but the only way I know of to make a video like this is to use a very nice high speed camera shooting 1000's of fps and then deleting all the frames between each cycle of the flow and splicing together the result.

  1. Well, the speaker is vibrating at the same frame rate as the camera, basically. So the vibrations of the speaker cause the stream of water (which is in lamina flow, where flow is predictable) to break up at a rate equal the speaker’s frequency, and then the camera is taking a picture at the same rate as well, therefore the effect is the same as a strobe or something like that, it’s just all the frames of the video are taken when the water is in the same place each time.

    • That was my thought, and the droplet effect is a probability issue…if the pressure and flow are kept constant, the droplet formation should probably form similarly (position, size and shape), and to accomplish that you would need the length of the tube past the speaker to be very specific so that it resonates in accordance with the frame/speaker frequency.

  2. The camera is recording frames per second at the same frequency as that the water coming out of the opening forms that particular pattern. You can produce the same effect 'live' by tuning a strobe light on to a stream of water.
    If you were to speed up the strobe light (or camera fps recording) slightly then it will look like the water is flowing in reverse :)
    Here's a nice example, with explanation and all:

  3. There is no strobe effect because you can watch the ssame particles of water if it was a strobe effect if would switch spots

    • No, you actually see different water particles each frame that are at the same spots as the ones in the frames before, like the other commentators pointed out.

  4. I dont buy it. The image ist constantly out of focus and very shaky which are IMHO signs of fraud. Repeat that video with a better camera and we can talk again.

    Some of the droplets look like they hang on a wire. For the stream it self, it is very simple to solidify water with some chemicals. Add the horrible image quality and we have a great fake.

  5. I found this video not even 3 hours ago while I was listening to some of Bibio's music . . . (Bibio is the same guy who made the song that was featured in that Google Glass add.) What a coincidence . . .

  6. the 'water' is probably a gel on a thread, hence the lack of focus to hide the thread between droplets, the sound is simply a recording of running water to give the impression of flow.

    • My first thought also. Spider silk or similar? The rest above explanations are too technical IMO to be correct due to the horrible camera work.

      Of course, I could be wrong too.

    Oh dear god….

    People aint just satesfied by breaking the laws, they have to break the laws a physics as well???…

    this is Totaly awesome! :D
    You learn something new every day.

    • Thanks for posting that link. That clears everything up.

      An analogy to this illusion would be the effects you see of a moving car, specifically the rims. You notice that if you reach a specific speed, the rims seems to stand still, sometimes even rotating inversely to the wheel. It's merely a trick of the eye. Our eyes capture 24 frames a second and splice those frames into a movie which is played back in our head. This is all the illusion of film.

      Back to the current topic, sound occurs in the form of waves. The frequency (rapidness) of the wave determines how often the water is spliced (Higher frequency = more droplets | Lower Frequency = less droplets). When you find a frequency that separates the water droplets by 1/24 of a second (under the acceleration of gravity), you will see floating water droplets. You notice when the water first exits the tube, it's still a stream, that is because gravity has not accelerated the water to match the speed with frequency. Just like the car rims, it won't work going 10 mph, nor 100 mph, you have to find the perfect speed.

  8. Could it be the same thing happening as when a staticly charged balloon gets close to a small stream of water? The charge from the balloon can bend the line of the water. With more static, it may bend more.
