Right, but it seems pretty controlled, is Liquid Oxygen super flammable? Because it barely caught on fire when he set the whole cup on fire.

Liquid oxygen is basically combustion in material form, not only is it very flammable but it can make things flammable that are not normally flammable.

Liquid oxygen isn't so much flammable as it is more or less fire waiting for a fuel. It will spontaneously detonate given most any heat source and fuel.

I mean I'm not saying don't dick around with liquid oxygen... But if you're going to do it at least do it outside, and maybe portion it out before you want to pour it on something. Don't hold a pint of it in a Styrofoam cup directly above an open flame. Oh and then keeping that container about 8 inches away from the burning material ready to be knocked over. I think he did something like that with liquid propane too that bothered me. Holding a large container of combustible liquid above an open flame in order to pour out a few drops.

Nothing terrible happened this time, but only through dumb luck. Compare to playing around with cup full of gasoline indoors. Also, he’s going to get cancer from the polystyrene fumes. Colour change on the canister paint was cool, though. https://www.youtube.com/watch?v=jBM8e_VOOqI

Not long ago someone posted the video where he froze gasoline with liquid nitrogen, and discovered that it could still ignite. He took advantage of this revelation by igniting the entire cup of frozen gasoline. It exploded on the table and scorched the ceiling.

Power Bottom posted:http://i.imgur.com/iT4MTJr.mp4 Excellent work by the drone operator, that's some stone cold professional camerawork. Most people would get a bit wobbly when they realise they're almost certainly going to witness someone die but this one just calmly maneuvered the drone into the best position to frame the collapsing chimney properly.  Also it looks like the digger operator was knocking bricks out off to the side to try and guide the chimney's collapse away from himself and it was only sheer bad luck that it was a direct hit, but on the other hand he's a loving moron for leaving something like that even partially up to chance. There's a reason demolition experts use controlled explosions from a distance.

I saw an OSHA report that someone was smoking in a high-oxygen environment, stomped on the cig to put it out, and the rubber/leather work boots promptly caught fire, and then the rest of him caught fire.

oohhboy posted:I wonder how much energy gets lost to space in an eruption that big. Lost? Almost nothing. It won't reach escape velocity which means it will come back down. A tektite is a piece of ejected material from a meteorite hit or volcanic eruption that went up high enough that when it came back down, it was partially melted by compression heating of the atmosphere in front of it. Depending on the main angle of explosion, Yellowstone cooking off could cause firestorms in the Amazon, for example. There's an impact crater in Thailand for which tektites were found in Tasmania and New Zealand, which is around the same distance.

Yeah Earth's gravity is too high for volcanic eruptions to reach escape velocity. It totally happens on lower gravity planets though.

There was an eruption from the Yellowstone supervolcano 1.3 million years ago which ejected 67 cubic miles of material and created a caldera 18 miles long and 23 miles wide, and that was the little eruption. There was another eruption 2.1 million years ago where 600 cubic miles of material decided it didn't want to be underground any more and popped up to say hello. It produced 2,500 times as much ash as the 1980 Mount St. Helens eruption.

Not a lot initially and proportionally, but in absolute figures the quantity will be huge because the entire event is huge.

It was close enough to both stop signs that'd I got to hear them rev up their shitbox ricers from both directions then crunch scrape crunch scrape as they bounced over it. https://www.google.com/maps/@44.7763489,-93.3297856,3a,75y,208.03h,66.22t/data=!3m6!1e1!3m4!1sA7STSjlzVS47wNoVoigE3w!2e0!7i13312!8i6656 The road is literally divided along the county line and neither county wants to deal with fixing it. It hasn't changed at all in the decade since I've moved away. IIRC the counties once joined forces to install the Dip signs on each side of the road while I lived there, and have done absolutely nothing at all since then.

This guy's an idiot, but this is not that bad in comparison to the rest of his videos. He should have used a shot glass to transfer for the LO2, but he wasn't in danger of the liquid oxygen exploding, or the potato chip vaporizing and blowing up the house---because that's not how oxygen loving works, jesus. The only real danger here was that he could have splashed his clothing with LO2, and then caught it on fire (briefly causing it to burn much hotter than usual, loving him up in the process). I'm honestly more concerned about letting all that liquid nitrogen evaporate indoors. I guess his kitchen wasn't enclosed enough for that to be a problem, but yeah, don't gently caress with nitrogen in an enclosed space

Platystemon posted:It would lose a shedload of energy to space through radiation. I asked because supposedly one of the reasons the Tsar Bomba got dialled back from 100MT to 50MT was that a massive amount of the energy would get lost to space rendering a bigger bomb pointless. It think it might have been other than all that engery getting radiated out was the fireball would have enough energy to "Get out" as it were dispersing outside of the atmosphere. The other reason was that it would generate an ungodly amount of fallout.
