Stone Rhino writes: "Yet another marvel has been created in the quest to create minature machines: a thermometer of liquid gallium within a carbon nanotube. The New York Times has an article on this. The thermometer is 10 microns long and measures temperatures from 120-950 degrees farenheit. Of course, the part I find most impractical about it is the fact that you need a scanning electron microscope to read it."

This first post... is too slow.

Sure the thermometer is small (2, Funny)

Anonymous Coward | more than 12 years ago | (#2992626)

But do you want that scanning microscope stuck up in your ass as well?

Well, okay, but do you want it in there the whole time they take your temperature?

Want a bigger anus? Now you can! (-1, Troll)

BME: When did you first realize that your ass could be the source of pleasure?

While watching porno films I saw women getting dick in their ass all the time and they seemed to like it a lot, so I thought I'd give it a try.

BME: What was it like the first time you stuck anything in your ass?

I was about twenty at the time the first time I tried it. The first time -- actually most of the first year -- I took no pleasure from it. But, I knew that the porn stars seemed to enjoy it, so I stuck at it and grew to love it as well.

BME: Why did you start putting larger objects in?

I saw gay films where men who were taking whole arms up their ass were getting pleasure from it. I learned to take pleasure from stretching my ass, and the wider I opened it, the more pleasure I took.

BME: How quickly were you able to move up to bigger items? Do you have a training regime?
It took me about two years to be able to take a wine bottle, and four years to take a 32cm ball. Recently I've been able to take a big ball, much bigger than the bottle. To pass that level I had to first train my ass with bigger bottles, like 1.5L pop bottles. There were a number of painful sessions with a lot of blood and ass-hurt for about four days after each session.

Because I am not comfortable writing in English, I will tell you my personal method in French.

BME: Thanks, I'll do my best to translate it for the readers. (Note: The following answer was translated by BME -- I apologize for errors in the translation.)

When I first started, I was using small bottles of shampoo. After that, I tried small apples, and then bigger ones. At this point I'd put a year of stretching in, and bought myself a large dildo.<p> My method was to dilate my ass as often as I could -- every day, even if just for a short while. Before starting it's important to use a large dildo; use it to both warm up and clean your ass, so make sure you stick it up all the way. When you find that you can take this large dildo without any work-up or preparation, then you know that you're ready to take it to the next step.

Then, in each session, to get your bottom prepared, put in a big cucumber. Soon you'll arrive at a point where even the biggest cucumbers you can buy at the grocery fit easily in your ass. Now you're ready to get serious. Buy a small Coke bottle, and use that in your ass. When that passes in and out easily, move on to bottles of wine. Once you can take wine bottles easily, you can move on to even bigger things.

If at this point you're having trouble with the 1.5L Coke bottle (just try not to force it out because the bottle is very hard), you can also have slower stretching fun with candles. Try putting them in one by one and seeing how many you can fit in -- at this time I was putting in about fifteen at the same time. The candles are great because they allow your anus to stretch very slowly.

Once the 1.5L Coke bottle can enter your ass, train every day or two (use a large dildo first, then the bottle every session). Most of the time I use Vaseline, but don't do what I do in this case. I think that the best lubricants are the ones you can buy for this in a sex shop.

When the 1.5L bottle is passing easily, go out and buy plastic balls that start at a diameter a little bigger than the bottle. Play with those, and with time, and a little luck, you'll arrive at my level too. (Don't feel bad if you're just beginning -- when I first started, I could barely shove a finger in my ass).

What I'm going to tell you now is very important if you plan on doing extreme sessions and taking large gauge. Do not bandage your ass. Do not tighten your buttocks. Try not to get an erecection -- you want the blood to be in your ass lips, not in your cock. It's not easy, but it's important that you think of nothing and empty your mind. It's absolutely necessary that you concentrate on your breathing. Don't think of the pain; know that it will pass. The real secret though is to breath -- and remember, without the pain, it's IMPOSSIBLE TO TAKE THE BIG ONES!


BME: What does it feel like? Is it sort of like getting fucked by a really well hung guy?

I want to make it very clear that I'm not gay -- I LOVE WOMEN!

BME: I'm sorry -- I imagine people must make this mistake all the time?

All the time, yes. Frankly I'm getting fed up with it.

BME: But you didn't tell me you'd gotten the idea for the bigger play from watching gay porn?

Yes, but the gay aspect never aroused me -- just the ass part. The films only helped show me that men enjoyed anal play as much as the women did.

I just want to find a woman who wants to play fisting with me (to fist me, or to let me fist her). I'm searching for one or two or more women to join me in my play -- I want them to stretch my ass with four hands at the same time while my body is supported. If there are any French women reading this, please write me -- it's my dream to do this performance.

Back to your earlier question, playing with a very large object feels a lot like having to take a shit very urgently. Even though you feel like you need to shit, that's just your imagination, and you can get extreme enjoyment with your ass so full.

BME: Do you like the way your ass looks when it's all purple and blown out?

Not at all, I prefer it when my ass accepts the stretching without any damage.

BME: Have you ever bled from the bigger objects?

[] Maybe eight or ten times I've had blood, but it was mostly because I didn't use enough lubricant.

BME: So... how big do you think you can go?

I'm looking for a bigger ball right now. I want to push my stretching as far as my body can physically support. I go slow though, because I never use drugs or anesthetics of any kind; I prefer feeling all the pleasure and the pain!

BME: What's the difference between pleasure and pain?

When I reach the limits of stretching, the pleasure and pain merge into the same feeling -- the pleasure this brings is amazing! Just two days ago I managed to put in a ball 37cm around (that's almost 15"). The feeling of pushing that out of my ass was indescribably pleasurable. Next time I do that I'm going to be sure to video tape it -- I'm sure I could probably even make money with that one!

BME: What are some of the objects you've stuck up your ass?

I've stuck up two big cucumbers at the same time, 1.5L and 2L Coke bottles, balls of all sizes, every size of wine bottle, lots of big butt plugs, etc.

I had a lot of trouble taking the 2L bottle because it doesn't fit in the ass gently. I can take a bigger ball, but a big rubber ball deforms to fit the shape of the ass -- it doesn't get smaller, but it's an easier fit.

BME: After a session, how long does it take for your ass to go back to normal?

Just five or six hours usually.

BME: Does it hurt afterwards?

No, not at all, but for the next few hours I can feel the ass's big lips.

[] BME: Are there permanent effects?

Yes -- my ass is bigger than ever!!!

BME: Do you need to wear a diaper? Does everything still work?

I'm not a baby!!! Everything is normal for me. All of the "anal destruction" I've done was done by me with care, and my ass is as normal as yours is... Although sometimes when I'm taking a crap it's huge because I've now got the capacity to really stock up. My digestion is trouble free though, and I've had no problems at all.

BME: What sorts of emails do you get from your fans?

Well, I don't know that many people online, but mostly admiration, asking for advice, and I've met a few other ass stretchers who've sent me pictures of their stretching.

BME: If someone wants to starting putting bigger things up their ass, how should they get started?

Take it slow. Start with little toys, and take your time growing your ass.

BME: Have you told any of your friends or sex partners about your ass play?

Oh, no! Up until now it's been TOP SECRET!

wickidpisa (41827) | more than 12 years ago | (#2992714)

you need a scanning electron microscope to read it.

I can't wait for the day that someone will figure out how to just hook bluetooth up to this thing :)

sounds interesting... (3, Interesting)

Hadlock (143607) | more than 12 years ago | (#2992719)

a better use of this (does this even have a use, other than proof-of-concept yet?) might be to, um, install one of these on nanobots, and have the liquid metal spurt from the end....somehow alerting the operator that the nanobots are about to overheat.

that's fascinating though, i was under the impression that carbon atoms were pretty small, and a nanotube would only be about 6 atoms across...from what i recall, lithium is pretty far away from carbon on the periodic chart. how does one fit one (or more) lithium atoms inside this tiny tiny tube?

Re:sounds interesting... (4, Insightful)

CounterZer0 (199086) | more than 12 years ago | (#2993126)

A) Lithium isn't very far away, it's element #3 (to Carbon's 6), so it's ultra tiny.
But that's irrelevant, as this thermometer uses Gallium is #31 (the first element to be predicted before it was discovered), and Gallium is much bigger than carbon. But that's why the carbon is arranged into tubes - multiple atoms across, able to hold gallium atoms.

What I want to know, is if using the SEM to read the temp changes the temp? All those impinging electrons must raise the kinetic energy of the Gallium atoms at least a little?

Re:sounds interesting... (1)

bgins (446545) | more than 12 years ago | (#2993206)

I was also thinking about the feedback effects of measurement, but from a different angle. Also, my physics & chemistry are admittedly weak:

Does anybody know if liquid Gallium, or any other suitable replacement, conducts electricity? Then one could measure the current induced by an electric field, or vice versa, to infer the temperature. I think these might provide less 'feedback' than an electron microscope, if the field and current measurement were also nano-localized.

Or maybe if is there a liquid dielectric of suitable scale, the temperature could somehow be inferred from this (using a wall of several adjacent nanotubes perhaps to create a varying area)?

Just some speculative questions... Of course, it'd be cool someday to see a nanocomputer.

Re:sounds interesting... (1)

bofkentucky (555107) | more than 12 years ago | (#2994344)

well, IANAC(hemist or Physicist) but I believe liquid mercury can carry current, apparently it was used in thermostats before people realized they didn't want carcinogens in their dwellings

Re:sounds interesting... (2)

caffeinated_bunsen (179721) | more than 12 years ago | (#2995662)

Gallium is metallic, and conducts fairly well (resisitvity=14.7 micro-ohm*cm, probably a bit different in the liquid phase).

The diameter of the tubes, as quoted in the article, is 75nm (that's a lot more than one carbon atom across). The average interatomic spacing of liquid gallium atoms is .26nm, if I did my math right. So the tubes are ~300 gallium atoms across. (BTW, these sound like some exceptionally wide nanotubes.)

As for changing the temperature of the thermometer by reading it, there is of course some change. But at that scale, thermal conduction is pretty much instantaneous, so you heat up the whole system (gallium, carbon tube, and whatever it's mounted on) at once. The change in temperature of the entire system from the electron beam is presumably negligible.

In a related note, British scientists... (2, Funny)

Single GNU Theory (8597) | more than 12 years ago | (#2992735)

...asked about carbon nanotube thermometers revealed about their own research: "These go to eleven (microns)."

For all the SI oriented people:
120-950 degrees farenheit
322-783 Kelvin

what is wrong with those SI units anyway?

Re:Celsius (1)

AddressException (187785) | more than 12 years ago | (#3017055)

I agree. Come on, were talking SI anyway (nano etc.), so lets do away with these ridiculous Fs once and for all.

It seems weird now, but... (2)

steve.m (80410) | more than 12 years ago | (#2993835)

When the First transistor [] was made, who would have predicted how we'd be using them now?

This thermometer probably isn't too useful on its own, but just shows that stuff you can build from 'big' components can also be done in nano scale.

I wish I was working in nanotech....

Re:It seems weird now, but... (3, Informative)

markj02 (544487) | more than 12 years ago | (#2994577)

The inventors of the transistor would have predicted it. The transistor was quite explicitly intended as a replacement for bulky vacuum tubes with inconvenient power requirements, and that's how we are using them.

impractical for now... (1)

PhuCknuT (1703) | more than 12 years ago | (#2995574)

But it's just one more component that could be a very useful thing to have when we start using nanotech and mems on a larger scale.
