Q:I have a liquid nitrogen dewar (big container) that part of the lid fell into. I tried draining it outside but it still has vapor escaping when I open it and is very cold..so I cant get the lid out still. Is it safe to leave open inside so it gets warm enough that I can stick my hand into it to get the lid out? How long will this take? (the container is probably 2 1/2-3 ft tall and Im pretty sure its insulated.

Q:I think I can sum up my personality as this:I'm focused on having the freedom to create and express my desires (both ambitions and sexual), and to be myself or whoever I wanted to be (whatever that may be), and I don't like anything that stands in the way. I like the sense of a youthful freedom, the freedom to create, and the freedom to fulfill all of my desires and fantasies.
Their are alot out their a spinning rod/reel combo would be the most versitale from panfish to bass. I would suggest spending a little extra that way you don't run into problems you can get alot of decent combo's around $100 at bass pro or cabella's. One thing to look for is the amount of ball bearings it does make a difference. I would suggest at least a 5 ball bear reel and a med. to med. Hvy rod in graphite its more sensitive. On the cheap side they sell a reel made by spider at walmart that has I believe 8 ball bearings and they run around $30 and you can get a tourney special rod at bass pro for around $29 bucks or a GS I think they run around 19 bucks. I personally use Pfluger President reels with 10 ball bearings and they have given me no problems in the first two years I've owned them, it's a good quality reel and I use bass pro extreme rods, they run around $110 for the combo in a spinning outfit. I spend alot of time fishing bass and catch some pike on occasion and never had a problem yet. Good Luck
Q:How could use use ionization-based smoke detectors?
For the majority of the day I would prefer 100 degrees fahrenheit, because it is often that hot where I currently live, but for being able to sleep at night I'd have to go with the 10 degree place. Also, are you talking fahrenheit or Celsius?

You are not supposed to use the school / college computers for playing, that's why they are blocked. When your IT department catch you, and they certainly will you can be banned from using computers at all. School It departments keep up with all the latest proxies by checking Yahoo answers. Easy peasy. Your parents will be notified as well. We pay taxes to give you an education, not to let you play on you tube . Work at school and play at home.
Q:Thinking in terms of the aluminum mast used on most production sail boats being like a lightning rod, as well as the highest point/ object on the water.
He is a GREAT wrestler and great on the mic, but to say face of the company? I dont know really, indie people like daniel bryand and CM punk had great careers but i feel like they still don't get treated right.. Hopefully WWE sees the pontetial in Dean and use him right. In Sheilds Promos Dean always steals the show with how hes talks. He can be the face of the company if only WWE is smart enough to let him. BQ: Hes a great heel. Absolutely hateful, i loved it when he called Hogans daughter a clueless *****. No offense to Brooke, but i always wanted Ray to turn heel earlier, i thought it was very strange how Ray was like this hero getting married with the icons princess. IDK the fans really hate punk. Especially a few years back. Punk using paul like that i felt was a Need. Him dying was tragic and unfair, but it was a opportunity to use it in WWE and make Punk even more evil. I don't think Punk even needs that hes hateful without it. I feel like TNAs crowd is more different than WWE. You cant really compare, thats my opinion.

I work in the Fire Protection industry and to be honest with you, there really isnt a market for 2nd hand extinguishers. You can just toss it in the garbage if ALL the pressure has been discharged from it. If you toss it in the garbage while it still has pressure, it will go bang when the garbage compactor compresses it and your garbage man will be pissed. Depending on the extinguisher type it *could* blow a hole in his truck. Also, depending on its size and type, it may be worth getting it recharged but it will probably have to be pressure tested as well (If its more than 5 years old) And that might cost you a fair bit. Small extinguishers between the sizes of 1KG and 2KG arent really worth recharging. The cost of a new one is roughly the same. You *can* recycle the extinguisher if you take it to the dump. They usually have special spots for old metal cylinders like your extinguisher. Also: If you wanna get creative, and you smoke weed (like i used to many years ago) you can actually make it into a bong which will make it a very interesting talking point next time you light one up with friends.
Q:how to tell if a woman is a gold digger or a social climber?
This is an attempt to explain the effects of gravity. Gravity really is the single most important force in the Universe, indeed it may turn out to be the only force if the various forces (electromagnetic, nuclear etc.) can be unified. Spacetime is just the name we give to the four dimensions in which we live. Length, width, height and time. You need all four dimensions to locate any point in spacetime. Now without gravity spacetime would be flat. That means that if you set off at a fixed speed in a fixed direction, you'd keep going in a straight line. Because of gravity however, this is not what happens. If you set off at a fixed speed in a fixed direction you will be deflected by the gravity of nearby stars and planets. Both your speed and dierction will change because of this. In order to visualise spacetime under the influence of gravity, we imagine spacetime to be curved by the gravity of stars and planets. This is just a visual aid though, a way of explaining why gravity changes the speed and direction of moving objects. It is pretty much impossible to visualise spacetime because you can't see time, the fourth dimension. What is important to understand though is that gravity changes (warps, bends, etc.) the four dimensions we use to measure the Universe.
