Another Insightful Question.....

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????
 
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.
 
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! "

In my best Archie Bunker voice - AW!! GEEZ!!!
 
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:)

Let me get that for ya;)

you think its funny....but thanks to my new lifting program, I've never been so inflexible in my entire life....need to spend an hour in the hot tub and an hour stretching....

I guess you need a new program;)

I'm not laughing AT you I'm laughing WITH you:D
 
yeah yeah yeah....the strength coach says...why do you need to reach behind you back anyhow....boys...they just don't get it....that or he expects me to go bra-less....never never never:)

Never??! Not even once??! Yeah we're a contemptible bunch to say the least.:angel:
 
The reason why nitrous oxide is used as
a propellant is that it dissolves in the liquid cream. When the cream
escapes from the can, the gas expands and in doing so whips the cream into a
foam. (This explanation is from the book "Food Science".)

Now, the interesting part is that nitrous oxide is an inhalation anesthetic
because it dissolves in synaptic lipid membranes. So it's not a coincidence
that nitrous oxide is a whipped cream propellant and an inhalation
anesthetic: nitrous oxide dissolves in fatty cream and it also dissolves in
fatty cell membranes.

Lots of things work as inhalation anesthetics; the better they dissolve in
the lipid membranes, the lower the pressure required. This is why spot
removers like ether and chloroform work as anesthetics in low concentration.
At high enough pressure, even nitrogen will dissolve in membranes; this causes
nitrogen narcosis in divers. Even an inert gas like argon will work as an
anesthetic since it will dissolve in membranes under enough pressure.
This is also why people sniff fat-soluble gases like propane and freon to
get high.

The high is not exactly a high, but a short period of disconnectedness and numbness from the body. Although it can be used alone, it is usually used in conjunction with other drugs, most specifically ecstasy.

I've tried it a few times, and it is not exactly my cup of tea, as I often get headaches shortly after.
 
Yellow...Hello Kitty:)..thanks for the imput...have you ever sprayed whipped cream up you nose trying it? If so does it hurt like getting water up your nose?
 
You definitely don't want to stick it up your nose.

Just hold it straight up, the liquid cream will be at the bottom, and the first few seconds, will spray only the nitrous. So you put it in your mouth, spray in the air, and then breathe it down. Then when the cream starts to go in your mouth, just seperate it from the air, or let go of the whip cream. Then you just sit there, and hold your breath. You'll start to feel a little dizzy at first, then you start feeling this strong pulsating feeling all over. Most people take two hits back to back. With enough nitrous, its like being taken away for a few seconds, and your thoughts are a little puzzled. Then when you start to come back, you're not really sure where you are, what you were doing. And then after you're done, you sit there and suck out the left over whip cream for desert. I'm getting a head ache just thinking about it.
