There was one narrow tube coming from the cylinders, and leading into a manhole cover, which made it all the more...

Liquid nitrogen?
Apr 20, 2007 by Bobbin | Posted in Chemistry
I was just wondering, if someone sticks their head in some liquid nitrogen, assuming they have enough air so they won't be starved of oxygen, will they die instantly? And if so, for what reason? I mean, will they die instantly because their brain freezes, or what?
Please don't try this at home =D
You will not be killed in a instant from liquid nitrogen. I have myself put my hand in the stuff for a couple of seconds without even feeling cold, and I guess I could do a few seconds more if I deared. You will freeze to death if you give enough time, but you will have enough time to feel pain.

They won't die but their face will freeze solid. If you then hit it with a hammer it would crack and smash.

They would die instantly ! The head would freeze completely - so completely frozen that it could be smashed to shards with a hammer !

Yes instant brain freeze causing a heart attack and shut down of all bodily functions. Not a good idea. About as good as the one i had. If you pass your hand fast enough through an oxy acetyline cutting torch flame will it burn. I thought not. Turns out it burned like hell..

Liquid Nitrogen?
Dec 28, 2006 by ask me | Posted in Chemistry
I asked earlier about an extra credit deal at my school where we have to freeze a steel pipe with chemicals and shatter it. Thanks to all who answered my question and it seems to be liquid nitrogen is the answer. I would like to experiment first because i need the credit. So my new question is where do i buy liquid nitrogen from and how much is it?
I agree, it is a dangerous substance. You would need to take many precautions. That being said, you can check this site for info:
Liquid nitrogen is not something that you should be experimenting with on your own. It is highly dangerous if incorrectly used. Imagine what you understand can be done with a metal pipe can also be done with ones fingers, eyesight, etc., etc.
What you are thinking of doing is NOT recommended........

Liquid nitrogen is very expensive and is not sold in small quantities. It would be better to contact local companies that may have liquid nitrogen for use in their laboratories or in their manufacturing processes or a local hospital to see if you could be allowed some supervised lab time. Many companies are happy to assist the local community and especially school students.
Examples of companies to contact:
Pharmaceutical manufacturers
Frozen food manufacturers
Hospitals or doctors specializing in dermatology (liquid nitrogen is used to "freeze off" lesions like raised moles or warts)
Good luck!
(PS - also freeze a blown-up balloon while you're at it. It's pretty cool!)

Where would I be able to buy liquid nitrogen and many other "fun" chemicals.
Many welding supple stores will sell compressed gases and liquid nitrogen.

Chefdruck Musings: Liquid Nitrogen Ice Cream at Lulu and Mooky's
by ChefDruck
The boundaries of ice cream are being redefined in a nondescript street of the Lower East Side of Manhattan, tucked between a pornographic art gallery and some closed down shops. If you take a taxi there, you'll be tempted to keep going, thinking that the rumors you've heard and the articles you've read about a cutting-edge new way of making ice cream instantly were wrong. The storefront of Lulu and Mooky's looks like nothing special, just another banal yogurt shop in Manhattan. But if you decide to skip it, you'll be missing out on a truly unique experience. The store manager has two ice cream bases to offer you: plain and chocolate. Once you've selected your palette, you can customize your ice cream with exotic fruit purees such as pear, apricot, or sour cherry, and with dozens of flavors such as honey, burnt sugar, and ginger. Once you've chosen your combination, he will pour the base in the mixer, add in the purees, ingredients or artificial flavor, and set it to mix for about a minute to get it frothy. Then comes the exciting part, the donning of the gloves, the retrieval of the containers of liquid nitrogen fro the vault, and the smoke that pours out of the Kitchenaid bowl as the ice cream base is instantly frozen by contact with the -195.8 degrees centrigrade liquid. After thirty more seconds of blending, the ice cream chunks will have thawed into a creamy mixture and your ice cream is ready to eat. The important question is, beyond the theatrics and thrills, is the ice cream actually good? It depends on the falvor chosen. My sister , husband, and I sampled three: grape, peach with honey, and chocolate peanut butter. The grape falvor was not from a puree, it was an extract added to the base in a spray bottle and the ice cream tasted chemical and strange, with only a faint whiff of grape. I would stay away from the spray flavors. The honey peach was good, although the fruit was still a little weak for my taste. When opting for fruit, I would suggest requesting...
