Another Insightful Question.....

[AGENT SHAGWELL]

What percentage of people have gotten high of of whipped cream cans?...and if so...did you feel like a dumb ass doing it?

 

[rudedawg]

Don't even know how to do it........ what show did I jsut see that on......2 chicks on a merry go round using the whipped cream cans????

 

[Big Buck]

you mean "whip its".....not me I've seen people do it, but I thought it was stupid. I'll stay w/ REAL recreational drugs thank you.

 

[smallmovesal]

sadly i've seen homeless people drinking hairspray and sniffing lysol and glue...


very disturbing.

I'm not sure if they still put nitrous in the cans as the propellant.
hell, I had the stuff at the dentist and it had no effect on me and he had to turn it off b/c he was getting high off of the stuff coming out from the sides of the mask on my face.

Ok what about helium.......I learned something new!!!...this and after doing shoulders bras that hook in the back are a BITCH!!!

"Helium is a non-reactive or noble gas. It does not cause any physiological or metabolic changes in your body.

In order to understand why your voice changes when you breathe helium, you need to understand how your voice actually works.

In simple terms, air moving past your vocal chords causes them to vibrate. By changing the shape of your mouth and throat, you sculpt the sound into normal speech. You change the pitch of your voice by making the space in your throat larger and smaller, and, to some extent by increasing the tension in your vocal chords.

Now we get to the science. In physics terms, your throat is a resonating cavity (this also applies to pipe organs, flutes, saxophones, and other wind instruments). There is a classic formula that describes these situations: velocity = frequency * wavelength. What this says is that the velocity of a sound wave in a resonating cavity is determined by the frequency and the wavelength of the sound. Now what is interesting about this is that the wavelength is determined by the shape and size of the cavity (your throat and mouth), and the velocity is determined by the density of air (which is constant).If you change the shape of the cavity you will change the wavelength which will in turn change the frequency.

Now the fun part. The only fixed part of the equation is the velocity. This part refers to the speed at which sound travels through air. What happens if you replace the air in your throat with helium? Well, it turns out that sound travels almost twice as fast through helium as it does through air. Ah ha! The equation tells us that the velocity has to EQUAL the frequency multiplied by the wavelength. Well, the wavelength is determined by the shape and size of the cavity. That part didn't change, so the frequency must change.

You experience this effect when you breathe helium. You try to talk in a 'normal' voice, but the gas in your resonating cavity has been replaced. Your brain puts your mouth and throat in the usual positions for making words(the size and shape of your resonating cavity remains fixed), and you start talking. helium has changed the velocity of sound in your throat, and as a result the frequency of the sounds that you produce are twice as high as normal.

I hope this helps you understand how helium affects your voice. Remember, when you breathe helium you are depriving your body of the oxygen that it needs. Always take a few breaths of air immediately after breathing helium. If you breathe it for too long, you will start to feel light-headed and dizzy. Prolonged breathing of helium could even cause suffocation! "

when people go into diving capsules, the compressed air in there has less oxygen in it b/c O2 is corrosive and even more so under pressure - so it has a higher nitrogen content. since nitrogen is lighter than oxygen, then it will move faster past the vocal chords and their voices sound funny.
not as dramatic as helium since it is significantly lighter.

this is also related to why people get the bends - the higher nitrogen content in the air and the high pressure will force the nitrogen out of the blood and into your tissues and joints if you rise to fast allowing the pressure to change dramatically without the nitrogen coming out slowly through your lungs....

scappy ass...your motto...what if you need money and love? should you work till it hurts and make people watch you when you dance?.....help please oh wise ass
