String Theory,..this is not detailed, but what do you think? Answered

Here is a short video (not embeddable, sorry) on the Higgs-Boson and string theory by Dr. Michio Kaku.  Comments?

I don't like the chopping camera-angles, it makes no sense; someone thought it would make things look more interesting but it's just a distraction.
Nice talk, everything does come down to vibrations in the end.

Oh and I didn't mean to imply that you were dumb or anything, just that the book I mentioned would be a bit much at your current knowledge level. I found it fascinating and have moved on to others like it (but I have a varied thirst for understanding and am also reading up on brain physiology/function, electrochemical reactions, and quantum theory, to name a few)....I find it fun to find out things....especially the things I can experiment with later (like electronics).

Yeah, I know. I know that the acid in a battery produces an electrochemical reaction with the metallic plates, producing energy; but solar cells, I know just that they do work!

Goodhart (author)colorex2012-01-28

Not all batteries (or cells to be more accurate) use "acid" however. But yes, the principle is nearly the same in all of them, no matter the chemicals used (nickel metal hydride, etc, & etc.).
Then there is plating, de-plating (stipping), oxidation, infusion, and many other things that can be done this way.
The world of physical-chemical reactions are also multitude however.  Take for instance simple glycerin.   Put a drop on a small pile of permanganese dioxide and you will have purple flames and smoke galore.

sugar, burned quickly and without much of an O2 supply will smoke like crazy.  A mix with potassium nitrate when burned will produce a fair volume of smoke.

Potassium nitrate... does that ignite with sulfuric acid?

And should it be powder sugar?

Select as Best AnswerUndo Best Answer

Goodhart (author)colorex2012-01-29

If one, under the proper conditions (again, this is NOT safe outside a controlled lab), burns sulfur and potassium nitrate, they can produce sulfuric acid. But doing this outside the lab can potentially produce enough of it in vapor form to give a person severe burns "from the inside out".

Oh, I remember now, school experiment: Sugar, potassium *chlorate* and sulphuric acid. Big fast flame, but not much smoke.

Careful though - that's one ingredient short of gunpowder. :D (Also, on a pedantic note, it's not non-toxic - even ignoring the fairly standard "if you eat this or rub it on your skin it will be unpleasant" effects, it's a known producer of human carcinogens.)

Potassium nitrate is carcinogen?? The first gunpowder had 1 x coal powder, 1x sulphur, and 6x nitrates... Is this right?

Select as Best AnswerUndo Best Answer

Goodhart (author)colorex2012-01-29

Yes, my apologies, I should have given the warning that it "can" become potentially dangerous; it burns brightly if not quickly, if enough "carbon" is present, and produces a lava like molten substance with potential to ignite what it is laying in, or other nasty offshoots. And yes, the sugar should be powdered. The amount of heat produced by a violent burn, can be hazardous in many ways.

Well, I'm careful by nature with chemical compounds. I plan on making smoke streamers for an RC airplane. I read on Wikipedia that potassium nitrate will melt with sugar at medium temperatures.

However, I need to know how to make sure that the mixture doesn't explode, but burns gradually. I know this has something to do with how it's packed into the tube that contains it. But I don't know for sure...

Hmmm, I have never been able to make "really fast burning" black powder (especially without the sulfur). It burns fairly fast, BUT not like gunpowder, more like a fuse :-) I am sure a little experimentation (done carefully) would yield results that would rival my experiences however.

I've never been able to make it burn THAT quickly....YMMV. Careful experiments should yield results similar to mine however.

No, it isn't a carcinogen itself; under certain (fairly common) conditions it can produce them (nitrosamines, specifically). It's a somewhat pedantic point because AFAIK casual contact with limited amounts of potassium nitrate (as opposed to potassium nitrite, which is itself a carcinogen) isn't actually going to hurt anything. But, y'know, still technically makes stuff that gives you cancer. :P
 
I dunno - Google it. :P Point isn't that it will magically transform into gunpowder, but that with that combination you have a very strong oxidizer mixed with a fast-burning fuel, which you ought to be aware of before you start. :)

*Seems I remember that wrong - potassium nitrite isn't demonstrably itself a carcinogen, but is similar to nitrate in producing nitrosamines and having a _suspected_ rather than a confirmed link to cancer.

It's eating it with protein, like in bacon & other cured-meats, that produces these nitosamines.
Technically "bacon gives you cancer".
