sorry but this one seems just plain funny.
It is really meant to have a quick way of testing any powdered substance that might come in the mail, etc.
So you handle, breathe, disolve the substance.
Bake in an oven at 75F for 20 minutes.
Bake in an oven at 75o F? Right. Go look at the temp dial on your oven. Why not just leave it on a counter top for 20 minutes. Most homes are 70o or so.
Add a protective cover, and insert into your cd rom drive.
Yeah, right. Try inserting a cd with a cover on it into your cd player.
You take a blank cd, put a drop of water on the inner circle, add the suspected substance.
Guess what? The cd player does not read the inner circle. That's why it's used to print things like batch numbers et al.

Re: sorry but this one seems just plain funny.
jar, you are funny.
Instead of trying to prove it wrong, try to imagine how it would be done. It was the science channel, not E!
Sorry RR but you stated in your Op "using your cd-rom to test for anthrax" and that my friend, negates almost everything you say in the rest of your post.
You don't ahndle it, only qualified people can.
Negated by your OP.
The oven they used was a labrotory oven, kind of looked like a toaster oven, probably used to speed up culture growth.
Negated by your OP. Also, 70o F is room temperature.
The cover was a thin pastic film, so that you wouldn't contaminate your drive.
Again, negated by your OP.
They probably use the inner cirle because there is no information there, and need a clean read.
No, it was a blank disk, remember? And guess what? There is information in the inner circle, it's where they print batch numbers and tracking information. There is no information on the writable part of the disk.
You can instruct your cd-rom to do whatever you want, if you know how to program it.
Well, no you can't. You cannot program a CD drive to read areas where the head cannot physically cover. If the head will not move over a spot because it is outside the tracking area, then all the programing in the world won't move the head there.

Where did I say it was a lie?
I don't remember saying it was a lie. Rather I imagine it most likely was an April Fool's story. It could also just be infotainment like the UFO shows, Big Foot, Alien Abductions or homepathic medicines.

Re: Thank God
That means it is an entertainment program. And absolutely none of the points I raised earlier have been refited.
We never doubted that you saw such a program. The only issues were those I raised. The implications that this is some new thing that will be used outside the lab or that the technology was as you described it is simply silly.

Re: Thank God
But I don't need to know how it works. What we are discussing is your presentation of the subject. It's entirely possible that you simply completely misunderstood what the program presented, but what this thread is about is what you presented in the OP.
You take a blank cd, put a drop of water on the inner circle, add the suspected substance. Bake in an oven at 75F for 20 minutes. Add a protective cover, and insert into your cd rom drive. With the software it uses the laser in the drive which has a resolution to 300 nanometers? to read the image left by the stain. Then a spectrograph of sorts pops up on your computer, and you can just compare images. I think it even tells you what it is, if it recognizes it.
and that is just plain hilarious.

Never had a problem with that aspect.
I can even see some advantages of such a portable instrument for field identification. It was the specific items outlined in the OP that I was discussing, and every single one of the issues I identified still stands.

Re: Thank God
Rat, please read Message 21.
In your OP you said:
You take a blank cd, put a drop of water on the inner circle, add the suspected substance. Bake in an oven at 75F for 20 minutes. Add a protective cover, and insert into your cd rom drive. With the software it uses the laser in the drive which has a resolution to 300 nanometers? to read the image left by the stain. Then a spectrograph of sorts pops up on your computer, and you can just compare images. I think it even tells you what it is, if it recognizes it.
That is what I was responding to. Anyone reading that who does not immediately hear the ringing gong of a BS detector needs some lessons in critical thinking.
Let's parse it.
First, the title of the thread is "using your cd-rom to test for anthrax". That was the first thing that made the red flares go off and the gongs start ringing. The idea of a home anthrax test is enough to make anyone suspect the remainder of the article.
Then you said:
You take a blank cd, put a drop of water on the inner circle, add the suspected substance.
Second flare goes off. Joe home owner is supposed to handle the stuff and dissolve it in water? But the drop on the inner circle which has no recording medium and also often has the printing for batch and part number? In addition, that area is beyond the reading track of most consumer CD drives, in fact the heads are specifically designed to avoid that area. Third and fourth BS flares go off.
The next sentence:
Bake in an oven at 75F for 20 minutes.
Bake in an oven at room temperature for 20 minutes? Rat, if you don't understand what that sent up yet another flare I don't know what more I can say. It is a totally silly idea. Why bake something at room temperature?
With the software it uses the laser in the drive which has a resolution to 300 nanometers? to read the image left by the stain. Then a spectrograph of sorts pops up on your computer, and you can just compare images. I think it even tells you what it is, if it recognizes it.
Okay, a possiblity as I have said before. But by the time you get to this point, so much BS has been detected that this seems like hardly worth pursuing.
I pretty much got it word for word how it happened, except maybe for the temp of the oven, which I may have not heard correctly.
Well, no you didn't get it even close. It is NOT something for folk to try at home. It does not appear that the material is placed in the unreadable part of the CD. It is still an experimental technigue that may someday hold promise for professional applications. And we won't even get into the temperature and oven bit.
If you weren't so busy trying to make me look like a fool, you might have learned something. I can't see how your approach is even remotely Christian.
I was not trying to make you look like a fool. I don't want you to feel like a fool. I never said you were a fool.
But You wrote the OP. I've tried many times in the past to point things out to you when it's obvious that you have missed the whole import of what was said. As I said, you wrote the OP.
You actually accepted the paragraph in your OP as a reasonable statement and did not see all the glaring errors in it. From this message it appears that you still don'r see just how silly that paragraph was. All I hope that I have done is to encourage you to examine ideas critically.
