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

  1. 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.
  2. Attach the vinyl hose to the garden hose (I used duct tape)
  3. 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.
  4. 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.

This is awesome, my friend! I've never seen anything like it, which is why I think you're on to a good thing! Thank you for sharing, and I hope it goes viral!

Aloha!

Class.Very nicely done dude.Votes & share coming your way. This is exactly the type of thing they should be doing in schools to help get kids interested in science etc. Great demo and steps too :-)

Thanks. It's a shame that schools don't incorporate this kind of stuff into their lessons. This video required all types of math, physics, film skills, and other sciences.

Awesome and interesting! Maybe you should find a way to market the project to science teachers...

Great hub; voted up and Shared.

hi

i bought nikon d5100 to made this experiment since it have 24fps

also i bought a big speaker, small water pumb to insure contious flow , and a rupper hose , and i bought a wave generator from ebay item number (321157000855)

i tried hard to get this fablous vedio recording

and i failed can you help

You really didn't need that hardware. All you needed was the software. I had an amplifier between my computer and the speaker (car audio amp) to increase the speaker movement. You can also download a free app to your phone that generates sine waves. It's free.

Wish to see what it looks like with "normal tv" frame/sec.
