What is the best thing you've done with liquid nitrogen?
For all of you who work in laboratory situations, especially for us senior year, you get to handle more and more substances on our own. For us, more recently we've been allowed the use of liquid nitrogen our research. It was a matter of seconds before using liquid nitrogen was not limited to our research. For example: – you have already tried freezing and breaking almost everything in the lab – pour in the beer, mix and try to drink (which is too fast it freezes) – jokes (it froze all just someones backpack before leaving the laboratory for technical assistance; try to fill a super soaker with it, unfortunately the expansion broke the weapon, but we have also succeeded in fire once and looked like a white gas firing flamethrower!) So those of you who have also worked with liquid nitrogen, and, what fun kind of things have you done? Maybe we'll try!
The statute of limitations should be out of it so that I can say. I had read a book called "Maryjane SuperWaba's Garden of Grass ", which he spoke of the weeds of freezing in dry ice to increase its potency. Hmmmm if dry ice would work, so that nitrogen liquid !!!!! If you try, is phenomenal, I do not think it increases the power, but wonder of wonders ", the seeds float. This means you can take without clean of weeds and put it in the LN2 and use a wire screen to remove all the seeds on top. Easy and clean. It once was a cockroach in LN2 for probably half an hour. When we took him out and let it stand, he began to walk! Roaches will inherit the earth. Did not do this, but I learned at Yale one of the teachers do an annual Christmas Day chemistry demo in which he wore a pair of goldfish in the LN2, pull one out and put it in water at which time it would for swimming. When going to start turning the other into the water to join the first, he "accidentally" drop it and break into pieces. The Humane Society Animals must not have been too strong at this time. LN2 ice cream is good, I made this one of the Boy Scouts for a demonstration. Throw it down and see that collect dirt. Finally a warning. I was using for degassing samples for admission into a depression because I was lazy and did not want to mix dry ice-acetone (Propanol dry ice is actually better because it syrup). I was trying to O2 in a reaction vial when I forgot and left the tap open while O2 balloon was attached to the variety. I heard a whistle and saw the balloon deflation. I dropped the LN2 Dewar from the road and saw with horror that was filled with solidified O2! It's not something I want to play. I have the hell out of the laboratory until hot.
