Here’s a video that will blow your mind, and give you a visual way to understand how audio affects the things around you – and inside of you.
The video, via brusspup, uses a clever trick to let you see how audio waves move a stream of water. When you see it, it looks like it’s a special effect, rather than just capturing what’s happening around you constantly.
Here what they have to say about the video:
This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.
The effect that you are seeing can’t be seen with the naked eye. The effect only works through the camera.
In essence, if you use a camera that can shoot 24 frames per second, and you play a 24 cycle per second sine wave, you can see the effects that the sine wave has on water or other things around you.
It would be interesting to see a creative application of this technique – and it seems well suited to electronic music.

Here’s another example of this experiment:
if you want to duplicate the project you’ll need:
- A powered speaker
- Water source
- Soft rubber hose
- Tone generating software
- 24 fps camera
Here’s their explanation of how you can duplicate this effect:
Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose. Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.
Turn on the water. Now look through the camera and watch the magic begin.
If you want the water to look like it’s moving backward set the frequency to 23hz. If you want to look like it’s moving forward in slow motion set it to 25hz.
