Unless you drink it liquid nitrogen isn't really that dangerous. You're not gonna freeze your hands off even if you put your hand in it, at most you'll get some frostbite and even then you really have to try.

Letting the liquid nitrogen become gaseous nitrogen in a confined space can mess you up though.

I have a few (careless) bartender friends and gently caress if every Towel Day some nerds don't get frostbrite from something. e: gently caress that's carbon ice though. Sorry, I'm drunk.

Wh.. why are these things all over New York City? For what reason?  I work, and hang out in downtown Cleveland, OH, and I've never seen anything like that. Also, I'm happy about that because I'd have a hard time not messing with one after a bunch of beers. Edit: Well crap, should've checked with Tom Scott first, I guess. https://www.youtube.com/watch?v=juZqGU9iuq0 Edit^2: And, because I'm thinking way too much about this now, how would you get liquid nitrogen out? Doesn't it have to be, like, "decanted"? i.e. flip the whole cylinder upside down, and then open the valve? I have an oxy/acetylene torch with O2 and acetylene, but I'm not about to use those cylinders to find out. BlankIsBeautiful fucked around with this message at 22:30 on Oct 17, 2017 |

The big ones I think have a tube that goes to the bottom so you open the valve and the gas at the top pushes it out. Little home- use ones you just take the lid off and pour.

In the UK it's easy as hell to get LN2 delivered. The hackspace I'm a member of picked up a 50l dewar cheap and setup a monthly refill service. It cost basically nothing, the money was pretty much paying for the special truck. They didn't ask any questions at all and we used it to make impromptu bottle rockets, made LEDs change colour by super cooling them and smashed pickles. One member picked up some superconductor stuff and we tried to quantum locking trick too. It's a lot of fun.

BlankIsBeautiful posted:Wh.. why are these things all over New York City? For what reason? This is how they make ice cream and cocktails now. http://www.telegraph.co.uk/news/uknews/law-and-order/11872399/Liquid-nitrogen-cocktail-Wine-bar-fined-100k-after-teenager-loses-stomach.html It works the same way your other liquid dispensing gas cylinders work. the valve is connected to a tube that goes to the bottom of the cylinder. When you open the valve, the pressure in the container forces liquid through the tube. There is a safety valve on the top of the container to vent gas off if the pressure gets too high. e: different use, same concept.  e: apparently those are to feed gas into phone lines to keep steam out or some poo poo. they just vent the expanding nitrogen gas into the lines.

That happened to a buddy of mine but they used less asphalt, or it was that bullshit they tamp into potholes, and instead of fusing like the pic it filled all voids in the body & fairings with the road. It immediately solidified and he couldn't get it out.

This happened to a major highway for evacuees leaving Houston and Beaumont during Harvey. For some reason the contractor had already dumped like truckloads of loose gravel all over the road they were supposed to be resurfacing which is already horrible in torrential rain, then by Wednesday morning there was tar all over the place. There's still tar on the roads in town. But how cool would it be to know that you probably lost everything that you couldn't fit in your car and you were just trying to get to family in Nacogdoches or Shreveport so you could regroup and all of a sudden your car is ruined? Good job lovely contractor, way to go. Enjoy the lawsuits from the insurance companies.

There's still tar on the roads in town. Looks to me like that is cheap seal, and that is how it is supposed to be applied. (Not supposed to drive on it while it is curing.) In which case I imagine the city or county's insurance may or may not foot the bill. (Due to ordering the evacuation.)

Oh dang, I'd seen this before but it was a shorter version which didn't show his young son walking underneath the stupidly placed ladder and then behind it. If he'd been standing there 10 seconds later he would have gotten all his teeth knocked out when it turned into a wacky battering ram. Setting up that ladder like that was incredibly loving  to start with, but doing something that reckless while your kid is in the immediate vicinity is  Edit: holy poo poo the full version is even better. Captain Shitforbrains forgot to take the extension cord with him so instead of climbing back down he got his kid to stand on the table and hand it to him. And after he falls the kid ambles back and just stands there with his hands on his hips staring at him. "Whatcha do that fer, pa?" https://www.youtube.com/watch?v=p8DI1kM6v0I
