Why don't you try to use mixer?

[grinellsmith]

@kihyeonj Or, you try it!

[grinellsmith]

yep, i think you're right. give it a try and lemme know how it works!

[RottingGumButchery]

I CALL BULLSHIT. YOU CAN'T SEE NO DNA! IT'S TINY! YOU NEED A MICROSCOPE FOR THST SHIT. I'M A SCIENTIST/GHOST HUNTER SO I KNOW! But srsly wtf? That shit should be small.

[grinellsmith]

@RottingGumButchery

Yeah, DNA is small, but you extract a bunch of it when it's complexed to a bunch of other bulky stuff, and you wind it around a fork, then can see it without a microscope. There are all kinds of examples of being able to see atoms and molecules with no microscope. Like, look in the mirror. You're made of molecules and atoms, and so is the mirror..

We did EXACLY this in a laboration in biology at my school. I already wrote my lab report but this was like a key for me :D What's the cooling for btw? Is it just for preventing the dna to keep breaking down afterwards?

[grinellsmith]

@Danne550 hi Danne550. That's cool. We didn't get to do any of this kind of stuff in my bio class. too bad for me.. btw, the cooling is just a way to get the stuff to come out of solution so you can see it. things aren't as soluble in cool solvents as they are in warm ones.

@dearanna

Well that's true in that I asked you if you had found anything as a paranormal researcher.

I assume that the answer is no.

If not, I would be extremely interested to hear what you have to say... not to mention the fact that James Randi would give you $1,000,000

[dearanna]

@Nilguiri No one's asking you to buy it. I definitely am not. I am simply trying to explain my personal views about the world and our reality as it exists today. You forget, sir; you brought this up first.

[Nilguiri]

@dearanna

Yeah, right.

You could say the same about leprechauns, fairies, pixies o for that matter, "god".

Not buying it.

[dearanna]

@Nilguiri The Sun being the core of our solar system was not physically demonstrable until the invention of the telescope and some very radical ideas at the time. The same thing occurs today. Antimatter is a great example of that.

Besides, I would love to be the one who definitively proves that so called "ghosts" don't exist. The fact of the matter is that there is no way to prove that they do not. I notice that you are basing your entire definition of "ghost" on the spiritual idea.
