Here's a good one that works without having to look through a camera.....It uses a strobe light. Very cool!

Now this is something i must try.


I would like too see this in a larger scale with more speakers, more water.


I'm thinking Lollapalooza meets Niagara Falls.

It'll even bring the aliens out, thinking we're smart and stuff.

Whenever you see videos of helicopters with the blades not turning, or cars moving forward when the wheels appear to be turning backwards, it's the same thing as this. Note that the instructions say to set the shutter speed to 24 fps, then diddle the audio generator between 23 and 25 hz. That causes aliasing between the water motion caused by the speaker and the shutter rate of the camera, and voila! weird stop motions and things that appear to be moving backwards.


Which to me, is kinda a big deal


Thanks for sharing Predator, big fan of your threads

That would be absolutely awesome


i wonder what wpuld happen if the water hose is set up between two speakers playing 2 different sound frequency's?

ive just watched the video and i havnt read any of the posts yet,
so maybe its been said already....
but is'nt that an excellent business opportunity right there
imagine the amount of people wanting that in their gardens
businesses wanting fountains
thats a million dollar business idea

amazing


I wonder what the wireless equipment does to us

I would like to see it with the hose locked in place. That would negate any influence the motion of the tube has on what we're being told is from sound alone.


The water in the hose was also moving in the vibrations, but the hose restricted the water so the hose moved instead.

Interesting. I see what you mean. :-)

In that case, Atlantis would surface and reveal itself to be a stargate run currently by Steve Irwin. I believe it was Jacques Cousteau who ran it formerly, until all of the bad press about eugenics.

Now it's your turn: one enormous speaker in a white tee-shirt, and two hoses pointed at each other...

I was building strobes and doing this stuff at maybe 10 years old, though. It's hard to believe that people aren't aware of it as adults. The fun parts of aliasing are when you start having to make sure you don't deal with artifacts in z-transform systems.

Noone would pay a dime for that. Human eyes dont work at 24fps
It's all because of the camera.

My first ones were a cardboard disk with a small hole punched in it, a 100W light bulb behind it, and spun by my Dad's variable speed drill.

I figured out how to pervert a car timing strobe with a function generator and a 12V supply not long after.

Dad snagged me a nice lab strobe that was old but still working ok from the base DRMO when I was maybe 12.

But I was a geeky farm kid, what can I say? There wasn't a lot of entertainment you didn't make yourself, we got 1 TV station.

Cymatics

See this Wikipedia weblink:
en.wikipedia.org...

allows the audible audio spectrum (less than 23KHZ) waveforms to be made visible
to teh human eye. In this case the videos DO take advantage of video camera frame
rates that make stroboscopic effects visible:

Stroboscopic effect Weblink:
en.wikipedia.org...

However SOUND does have more interesting properties which can be made visible
such as Sonoluminescence which can allow ANYONE with a soundcard on their
computer and some high frequency drivers to make water glow like a lightbulb.

Sonoluminescence Weblink:
en.wikipedia.org...

or for those of more who like the more SINISTER side of things
how about an Acoustic Cannon:

Long Range Acoustic Device Weblink:
en.wikipedia.org...

...or...

Acoustic Levitation Weblink

what I find interesting about cymatics at least in some experiments the same pattern appears according to the same frequency even after going up in frequency and then back down to the original sound. Like the ones that look like a tortoise shell or sea creature shapes or insects when you reach a certain Hertz, they reappear the same while each individual particle is moving around all the other particle the overall structure is the same. it's got to be some kind of fundamental law or something that probably has some connection to the strings in string theory or how the vibrations of the strings fuse matter into shape. I think cymatics are separate from consciousness though. Cymatics has to do with matter and motion, I don't see any connection with sentience or being.

on second thought I don't even know what the crud I'm talking about I just love watching those videos

I don't understand. Why do you need the camera? Can't you just do the experiment and watch it in real life and amaze all those around you? Or is it only visible on a camera?

Ah, now I see
Optical Illusion, basically. Star for you, my well coiffed monkey friend
