Reminds me of a story which my sons primary school teacher told us and it follows thus:

 

She was asking the class if they knew anything about the octopus they cared to share with the rest of the class..............well my sons hand went up quick as lightning she said...............

So she asked him to share his knowledge with the rest of the class and you know what he shared.................Well it was this.................as follows:

 

Not forgetting he was only 5 years old at the time............

 

"Please Miss" he said "They have eight testicles!"...............Well she told us that she nearly wet herself inside laughing like mad at what my son had said but she had to maintain her decorum so she thanked him for his answer and amazingly the rest of the class obviously thought he had said tentacles........phew what a relief and now at 19 years of age he laughs everytime we remind of the fact hehe!! :D

 

What a joy children are yeah!! :D

He had balls to come up with an answer like that..... ;)

Fact #2

 

Sound at the right vibration can bore holes through any solid object, including diamond.

 

Really?? That's pretty cool.

 

I remeber all that Jazz about using resonance to destory things like building and bridges but definitely didn't know that.

I remember being at a gig once where the bass guitar was eq'd such that it made a load of people throw up!

 

Didn't the Mythbusters do a show including this myth and disprove it?

They did the brown note which deals with output from the other end. But for that they exposed Adam Savage to the full range of frequencies from stadium speakers right next to him so i'm pretty sure that means no amount of sound can cause problems to the body.

 

In this cause it was probably the extreme volume causing the inner ear problems which i suppose could cause motion sickness....

48 hours of Surfin' Bird and you might end up smashing your head off a wall :p

Depends on the volume. I was fascinated at school when we were taught that the majority of the damage caused by an explosion is actually by the sound wave it creates.

Yeah it's all air pressure, we just percieve it as sound

Ok...seeing as it is generating interest, some facts based on this...

 

Fact #3: Soundwaves / shockwaves with a force of 35PSI (Usually generated from a Sonic Boom by fireworks or fire crackers, or breaking of sound barrier) can injure the human body.

Fact #4: Soundwaves / shockwaves with a force of 100PSI (generated by C4 explosion at close range, hand grenade explosion) can kill.

Interesting, although I am sure the explosion & shrapnel itself will do the job :p

the US Army tested it by generating the force using a pinch (EMP/Shockwave generator), and using shockpads (which test PSI) and the conclusion was if the explosion and shrapnel left the person unharmed, the shockwave would do the job, and they are now working on devices that could generate the same force and fit into a grenade sized device.

Awesome. I want a shockware grenade!

The shockwave from an explosion will often atomise a person. A lot of coffins being repatriated are weighed down with sand. It happened to a number of friends one day in '79.

The principle is that all waves have a frequency, and energy.

If you were far too brainy/nerdy, and you could calculate the energy required to break a molecular bond, and the frequency at which that energy is matched, you could cause the molecular bonds to break.

 

Within the human body, the principle is that the body operates by signals sent down the nerves from the brain, and these signals have a frequency attached to them that the brain operates on. In theory, if you directed the right frequency at the right place, you could interupt the signals from the brain.

The chances of finding the exact frequency that works on the exact part of the body that you want to control is really damned small.

Shockwave effect or exceedingly high db sounds is a lot more likely to have the desired effect, since inner ear's are rather sensitive.

Fact #5: Feet sizes in England are measured in Barleycorns

 

For those of you that haven't Googled it already

 

# English unit of length equal to 1/3 inch
