An Amazing Water Experiment
I frequent YouTube to say the least.
I frequent Youtube, to put it lightly, and I do have several Youtube channels. On one of those channels, I go by the name AricDaNinja (youtube.com/aricdaninja if you ever want to check me out). I am always looking for the next best thing to watch, or the next best thing to film. Recently by chance I came across an amazing video incorporating sound and water. The experiment looked intriguing and the results looked unbelievable. They looked so unbelievable and fake even, that I had to give it a try. That's just how I am. I mean, I had been meaning to buy a new camera for other Youtube projects anyway. So I did just that.
Was it worth it?
I swear that the next few days seemed like an eternity as I waited for my brand new camera to arrive. I decided to buy the Canon Vixia m500. (No I'm not trying to sell you one, but it's probably the best out there right now for the money, $499). And let me tell you, it was well worth the wait. Within the first day I had acquired all the materials I needed, and filmed all the footage I could ever want. The camera exceeded my expectations and that's a modest statement. The camera is awesome! More importantly, the experiment was a huge success. The results were astonishing.
Here's how I did it
At first you'd think this is some sort of computer animation, but I assure you it's not. This is a project you can do at home and you probably don't need to buy anything.
Here's a list of must haves:
- A 24 frame per second capable camera (crucial)
- Tone generating software capable of producing a 24 Hz sine wave. Audacity is the easiest to use and it's a free internet download. http://audacity.sourceforge.net/
- A speaker. The larger the better. I used a 12" Infinity Kappa with a 700 watt amp. I went a little overboard.
- Clear vinyl hose. I only had to get a few feet. These hoses produce better results than a regular garden hose.
- Duct tape. The hose won't hold itself.
Some simple steps
- The first thing you need to do is find a place for the speaker to sit. I used a 5 foot step ladder and secured the box with bungie cords.
- Attach the vinyl hose to the garden hose (I used duct tape)
- Secure the hose to the speaker with duct tape. You'll notice I secured it directly to the speaker which you don't have to do. My woofer is made from polyurethane so it doesn't get damaged.
- Run water and produce a 24 Hz sine wave. Keep in mind that the results are not visible to the naked eye. You'll see them in your playback or viewfinder, as long you use a 24 FPS camera.
How it works
A 24 Hz sine wave is a very low frequency sound. Humans can barely hear it, but the speaker is moving. It's moving at 24 times per second. When you use a 24 frame per second camera, it picks up 24 frames that essentially look exactly alike, resulting in a freeze effect. The water changes shape slightly in each frame so it still looks like it's flowing, but the pattern is always the same in each frame. 25 Hz shows a forward effect because there is one extra speaker movement within that second. 23 Hz shows a reverse effect because there is one less speaker movement. Simple. Ok, maybe it's not that simple, but it's doable.
Remember to have fun! If you have only a 30 FPS camera, try it at 30 Hz. However, I doubt it will work since most 30 FPS cameras are actually 29 FPS cameras. You never know what the results will be until you try it.
