Liquid Nitrogen?

Question

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?

Answer 1

I agree, it is a dangerous substance. You would need to take many precautions. That being said, you can check this site for info:

Answer 2

you can find wart remover in a can. This is liquid nitrogen. Be sure to read the instructions very closely, and by all means do not spray it directly on your skin. I'm not sure you could use it the way you want to, but you could shatter other things to prove that it works, like things made of rubber, or plastic.

Please note that shattering metal could result in small shards flying... so be sure to protect your eyes and skin, and only do it in the presence of your parents.

Otherwise, call a local college and ask if someone will help you try the experiment.

Answer 3

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!)

Answer 4

it may favor to be a fabrics that both does not change into brittle or continues to be sufficiently reliable at extremely low temperatures. i trust that particular metals like tungsten or titanium does not actual shatter if hit difficult after being dipped in liquid nitrogen, even although their cloth houses would replace critically on the low temperature.

Answer 5

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........
