The nitrogen will spray out the end of the tubing onto you or the audience, etc. so use care that you have protection on the hand holding the tubing and that there is enough distance at the top of the tubing for the nitrogen to vaporize before contacting with people. Although the tubing is flexible at room temperature, at liquid nitrogen temperature it becomes brittle and will shatter if hit with a hammer or whacked on a lab bench. If you twist the tubing around itself before putting it in the nitrogen, the tubing will uncoil itself as it thaws, in a sort of serpentine manner.

Quotes From the Film Boondock Saints

Quotes From the Film 'Boondock Saints' Two Irish brothers, Murphy and Connor, feel that theyve been authorized by God to clean up the underworld. Predictably a lot of blood, gore, and swear words follow. Each Boondock Saints quote given below is representative of the colorful dialogue that abounds in the film. Connor Well, a penny saved is worth two in the bush, isnt it? Connor You look like Mush-mouth from Fat Albert. Il Duce The question is not how far. The question is, do you possess the constitution, the depth of faith, to go as far as is needed? Monsignor And I am reminded, on this holy day, of the sad story of Kitty Genovese. As you all may remember, a long time ago, almost thirty years ago, this poor soul cried out for help time and time again, but no person answered her calls. Though many saw, no one so much as called the police. They all just watched as Kitty was being stabbed to death in broad daylight. They watched as her assailant walked away. Now, we must all fear evil men. But there is another kind of evil which we must fear most, and that is the indifference of good men. Murphy Were sorta like 7-Eleven. Were not always doing business, but were always open. Murphy Do not kill. Do not rape. Do not steal. These are principles which every man of every faith can embrace.

Rocco Ill catch you on the flip side. Yakavetta The 90s are killing me. I shouldnt have done that. Youre not supposed to tell a guy youre gonna kill him no more.
