This is great, what happens if you install a water hose onto the speaker, let the water run along side of it and adjust the speaker volume? Well the water starts to dance and shape all sorts of cool patterns depending of the frequency and volume the speaker is creating.

Check the most intriguing water and sound experiment and watch the water shape into a nice looking sine wave.

As taken from the YouTube page, to try the experiment yourself, you will need the following:

- A powered speaker
- Water source
- Soft rubber hose
- Tone generating software
- 24 fps camera
- Tape

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.
