Sound or nanobots create water snakes???

Now it is generally common knowledge that if you project sound waves at a note of C, at a glass with a resonant frequency of the note C, long story short the glass will vibrate and shatter.

Sound energy and sound waves, if intense enough or at the correct frequency are able to interact, move and destroy objects.

Now if say.......for example if sound waves are projected in a certain way.....would it be possible to create a pillar of water???

Or could you pour nanobots (when the technology is advanced enough obviously) into the water, each one designed to latch on to water droplets. When these nanobots interact they could make water rise up in a pillar or as a snake thing (im thinking of the film "Abyss")

Or is there something you would like to mention on this line of talk???

Well honestly I cant give you an answer on that, though you could create one with a kind of gravity control system, but that is straying from the topic.

perhaps this should be on the military forums.....

what note do brains vibrate at- everything has to have a note SOMEWHERE...

Take a tuning fork and tap it on your dome. Note the frequency then play back that frequency at a much higher amplitude. Skulls are brittle.

Sure I would imagine it to be possible to create a sort of coherent snake like object from water using resonance frequencies.. it would be a rather large and awkward contraption eminating waves from all directions to contain and manipulate the water from every angle, otherwise it would just spew out the opposite side.

Dunno about the nanobot idea, we don't have advanced enough nanotech at the moment for me (or anyone, I think) to make an educated guess on that point.

As for the sound waves, every object has something called a 'resonant frequency'. I may be botching the explanation somewhat here, but basically any object that encounters a wave at the resonant frequency will start oscillating, or even destroy itself.

This is why the glass shatters at a certain note. If you have heard of the Tacoma Narrows bridge disaster, that is why it collapsed; the wind oscillated the bridge at the resonant frequency. I also read of a case in Russia where soldiers marching across a bridge in lockstep happened to march at the resonant frequency of the bridge, and it collapsed under their very feet.

Water has a resonant frequency as well. In fact, if I remember correctly, that is how a microwave heats food. The microwaves frequency is the same as the resonant frequency of water, which causes the water molecules in food to vibrate, which heats the food.

So, I suppose if you had a really big energy source that was generating waves at the resonant frequency of water, you could get some really weird behaviour, but I have no idea whether it would produce the pillar you describe if a sufficiently massive wave generator were used on a large body of water.

(BTW I am no music expert, but aren't there multiple 'C' notes, i.e. different octaves? There's only going to be one frequency, and thus one 'C' note, that would shatter glass, unless it is something other than frequency that distinguishes the different octaves.)

i no bout the different octaves etc i was just being brief.

Folk knowledge, maybe, but no truth to it. You'd find that different frequencies shatter glass, depending on what else is in the glass (impurities) and how thick it is and what its shape is, and so forth.

Nope. There's limits to the height that a column of water can rise. Even vortex columns (waterspouts) only have a certain limit in height. Nor is there any way to focus sound tightly into a column. It tends to form cone shapes.

Or could you pour nanobots (when the technology is advanced enough obviously) into the water, each one designed to latch on to water droplets. When these nanobots interact they could make water rise up in a pillar or as a snake thing (im thinking of the film "Abyss")

In science fiction films (particularly in films) where the producer and scripter are not necessarily faithful to science, ANYthing can happen. While many of us think that they could make far more exciting pieces following what would really happen ("10" comes to mind with its overblown script and truly terrible science), sadly, some of them will abandon good science for theatrics.

In this case, "probably not." You're looking at height versus weight and stability and anything over about 32 feet needs a lot of support. It'd probably just sink.

Hypersonic Sound

At NextFest 2005, a sort of inventors convention, a method of focused sound was introduced. I found the "how it works" part unfulfilling myself, but the technology seems to exist.

to break a glass you need to find its frequency and it depends to a lot of things as Mr. Byrd said.

to do that you could just keep on trying or, just hit the glass with a stick and record the sound it creates, and in a sound editing program cut the clean sound of the glass and loop it seemlesly and play it back to the glass amplified. or you could use a tuner and later play that note if you want to avoid computers.

this is called ressonance, you can even demolish walls or shake the ground with this method as long as you know the right frequencies and have the means of powerfull transmiting devices.

ever heard the story of the battalion of troops and the bridge.

this is all incredible, i must say. im reminded of an old book, the calculis affair. a destructive device such as this was put forth as a huge weapon that could level citys. just have a large powersorce, and have a computer send out frequencys up and down the spectrum, analize the results + a rough aproximation of the shattering point of concrete or steel... you could (theoreticaly at least) level entire citys.
