This is the kind of shit that makes this forum better than others.

Old dudes from different parts of the planet, getting together to play Ping Pong on a Sunday afternoon, sort of. Well, close enough. :)

Why don't they just include a little vial of sulfuric acid for people to light their matches?

Whose house it that and why?

Never piss off a Swedish chemist. :o
According to the comments section, it's a show called "Don't try this at home". It supposed to be designed to teach kids what horrible things can happen if you play around with chemicals.

In other news, Sweden burned to the ground last night......

Fucker probably killed every sea creature in that lake by raising the pH. :x :x :x

Still, I've never experience the kind of joy and satisfaction that young man is experiencing, and probably never will. :cry: :cry: :cry:

Oh come on now bud ,I'm sure if you put your mind to it (given yer expertise displayed on here) you could cook up something that would wipe out 90% of humans. Don't sell your self short. Buck up...look for an evil over lord... heck become one yourself...The planet is desirous of a dictator. It could be...YOU!

There is a glove on the floor in the bottom of my stairway.

It's been there for months. Pisses me off, but every time I see it or remember it, the guilty child is asleep or away somewhere.

I would pick it up myself, but I dare not risk a back injury. Back sprain pains don't go away completely anymore. In fact, all minor injury pains don't go away anymore. They just add to the total aches and pains of everyday life, which steadily increases with each aging day.

That glove is there right now. Minor things that piss me off don't really go away anymore. They just add to the total pissiness that I feel all the time, which steadily increases with each aging day. Found another skin tag under my arm this morning. That pisses me off too.

What I'm trying to say is that I don't think I would make such an awesome world dictator anymore. :oops:

It's said that from a certain age on if you don't hurt somewhere, it means you're dead – but that's a lie.

What is true however is that there are loooooooooooots of fucks you don't give anymore. :wink:

Thanks Witness. That really is about the only good thing about getting old: The diminishing number of fucks one must give. About anything. Any fucking thing at all. :-)

Use a tool to acquire it if it really is tricky, then place it where the guilty child will have to move it to do something they want.

Reminds me that I need to order another liter of benzyl alcohol tomorrow.

Funny, seems like everything with prefix "benz" has been black listed or at least made very expensive, except for benzyl alcohol.

I wonder if there are any benzyl alcoholics out there? They probably drive around in Mercedes Benzenes. :P

Enter the name of a chemical and you can see its structure in either 2D or 3D.

E.g.
methyl ethyl ketone
2-(pyridin-4-yl)ethyl carbonochloridate

I guess you need to know what color represents what kind of atom. I'm pretty sure that carbon is black and hydrogen is blue. What about red and green though?

The small blue ones are hydrogen, the big ones nitrogen, oxygen is red. But sulfur also gets a black sphere…

Carbon prefers 5 and 6 membered ring formation. A 4 membered ring would be very difficult to achieve. I would say it's impossible, but as soon as you say something is impossible, some mad scientist makes it his his goal in life to prove otherwise and ends up creating things like



So I'll just say that a cubic buckminsterfullerene is unlikely. :P

The smallest one ever made that I'm aware of was made of all 5 membered rings:

What'd I tell ya.....from the article:
Before this work, researchers believed that cubic carbon-based molecules would be too unstable to exist.
Somebody said it was impossible, then Phillip Eaton and Thomas Cole said fuck nature and it's silly rules, and what did they make?
Having high energy but kinetic stability makes cubane and its derivative compounds useful for controlled energy storage. For example, octanitrocubane and heptanitrocubane have been studied as high-performance explosives.
Ha! The fools at the academy said it couldn't be done, but after years of burning through all our grant money by experimenting with ludicrously dangerous and unstable chemistry, we gave God the finger and created something that shouldn't exist. Behold, we bring you......

Good find, Mr. Witness. :D

I'm having fun perusing through the aftermath of the discovery of cubane. It made me wonder why cubane isn't as well known as TNT and other explosives. Turns out that making it is dangerous, expensive, and the end product isn't as explosive as originally though because, heh, it's kinetically stable.

So even after the grand reveal of cubane, the scientific community collectively said "meh" and promptly forgot about them. Ouch.

I tried searching on youtube for a video of a cubane explosion, or even an octanitrocubane explosion, but apparently no one has attempted to make the stuff since the invention of Youtube. I did find some fun stuff while looking, like this:

I actually heard about it when I was still a student: the brother of on of my friends did research in chemistry and got very excited about the new synthesis of cubane. :)

I liked the vid about nasty stuff; here's another reminder about the dangers:
Wikipedia wrote:Karen Wetterhahn (October 16, 1948 – June 8, 1997) was a professor of chemistry at Dartmouth College, New Hampshire, who specialized in toxic metal exposure. She died of mercury poisoning at the age of 48 due to accidental exposure to the organic mercury compound dimethylmercury (Hg(CH3)2). Protective gloves in use at the time of the incident provided insufficient protection, and exposure to only a few drops of the chemical absorbed through the gloves proved to be fatal after less than a year.

Keep safe, Bruce! :wink:

I remember when that happened. It was the year I graduated from undergrad. My own brushes with death in the lab include a sodium explosion, a peroxide explosion, and accidentally boiling potassium cyanide, which released cyanide gas.

Yes, it does smell like almonds.
