It's OK they didn't inhale. Afterwards they settled down to watch a film about a giant gorilla...

I plan to use some of the hot air to cook some popcorn.

If two totally different systems both achieve mediority it sugests that anyone claiming that one of the systems is particularly good isn't paying attention. Also, if one of the two is significantly cheaper many people may prefer cheap mediocrity to expensive mediocrity.

I'm not sure what you find surprising; is it the fact that the man makes a good point, or the fact that properly organised socialised healthcare is cheaper than having someone make a profit from it?

From your point of view, Ebay is probably the "usual chemical supplier". Some red inks are based on eosin and some blue/ black inks are based on crystal violet, but I don't know how useful those dyes are as histological stains

"Free Energy is everywhere" No it's not. Just because you keep saying it doesn't mean it's true.

Well, this "Dyes are bought from usual chemical suppliers." from CharonY is the right answer. What more would you like us to say?

If you didn't pay for phase contrast you almost certainly didn't get it.

Copper chloride changes colour markedly as it gains and looses water. IIRC the anhydrous form is brown and with increasing water it turns yellow, then green and finally blue. You won't get CuCl ions but you will get something like a hydrated CuCl+ ion [Cu(H2O)3 Cl]+

I ought to be able to identify the verbs in a sentence and then work out what nouns are the subject and object of that verb. That sort of analysis of the sentence is called parsing. I believe there are similar processes in computting where the system works out what are data and what are instructions; these processes are also called parsing. The point is that I couldn't do it with the OP.

I didn't understand most of that but I think this remains both relevant and ammusing. http://xkcd.com/622/

It seems to me that someone who thinks that a single person's experience is adequate data on which to base a response, is displaying exactly the sort of bias that the OP was seeking to avoid. On the other hand I suspect that practically everyone has at least some bias with respect to this question. I know I have a fairly strong opinion on the matter so I'm not giving an answer.

H2O2 isn't ordinarily a solid, did you mean percarbonate or some such?

That was a problem, but not the reason why it was banned. This was. http://en.wikipedia.org/wiki/Phossy_jaw It hardly matters- there's no white phosphorus in matches.

"The thing it cant b impure is that when i re crystallized it, Nice blue crystals were formed. " Recrystalisation is pretty good at removing impurities so you can get nice blue crystals from a solution that isn't very pure. Also, since solutions of copper sulphate in water are blue and your stuff is green you have an impurity whether you like it or not. The most probable impurity is chloride as UC explained.

Is it just me, with my my odd sense of humour, that finds it funny when someone called "verb" posts a question that I can't parse, never mind answer?

"So here I am again braving it to ask you all what do you think of this.. I have been recently looking into free energy with magnets" I think you should stop. It is difficult to think of anything more robustly guaranteed to be a waste of time.

Table tennis anyone? Obama Lama ping pong?

Bicarbonate of soda gives CO2 and H2O on heating.

Do any of the starting materials absorb at 1641 and 1562? If you started from an acid halide does the corresponding acid absorb there? If not then the evidence is pretty good that you have an amide.

"No, the baby boomers (at least in the US) are a WW2 thing. They're retiring right now" That's debatable, the peak seems to be in the 60s. http://en.wikipedia.org/wiki/File:Birthratechart_stretch.PNG More importantly, if you are right, then they will be even more convincingly dead by about 2050 when the magic graph hits some arbitrary number. I still think this is focusing on the wrong issue. Our population is aging; how do we pay for pensions and old folks homes?

I know this looks a bit like a plug, but I have no commercial links to these people, honest. I'd be happy to get just about any of the t shirts etc from here. http://store.xkcd.com/

Never mind the details. You are just plain wrong. Zn is more reactive than Fe.

The "baby boom" was on its way out when I was born (1965). So the babyboomers will retire about 2030. If they live to be 80 (most won't) they will be dead by 2045. That graph predicts a "problem" in 2050. Since practically all the babyboomers will be dead by then and most of them will have died long before then, I don't see how they can (directly) be the cause of the problem predicted for 2050. Of course there's every chance that the regulations will have changed by then. The most obvious solution is to raise the retirement age which should increase tax revenue and reduce social care spending. It doesn't matter if the healthcare costs are met by a nationalised healthcare scheme like the NHS or Medicare or by private healthcare insurance. The costs of an aging population will rise. New developments in medicine will often also increase the bill. Somebody has to foot the bill, and arguing about the relative merits of public or private insurance is like rearranging the deck chairs on the Titanic.
