Look THIS up: years ago, a bunch of engineers had an annual barbecue. As with all barbecues, the big-deal was getting the charcoal going, and waiting for it to get good and hot before starting to cook. Being engineers, they started working on a solution. Over a few years, they used different starter fluids, and fans, and propane torches, then acetylene, and then somebody thought, "oxygen". By then, it wasn't about the barbecue any more; it was about how to light the charcoal the fastest. So they rigged a way to deliver oxygen gas to the grill, and finally, one year, they just poured liquid oxygen on the charcoal and set THAT off. Destroyed the grill, but lit the charcoal in something short of a second. It was at some college I think, maybe M.I.T. or Cal Tech. Anyway, the story is semi-famous. I suggest using keywords, "engineers barbecue charcoal oxygen" all together for one search. That oughta turn it up.

For anyone wondering, wearing gloves when handling liquid nitrogen is more dangerous. It can seep into inside the glove and burn your hands, while if you bare hand it will just slide off.
I used to work with cryogenics. We used a 600 to 1 expansion value as a ballpark value. That's why that bottle took off. The LN2 expanded instantly 600 times within a confined space with a makeshift "nozzle" when he inverted it. Pretty cool.
@@toohda Similar. The pumps must push 20 tons of fuel per second to power the rocket. To get the energy to power the pumps, some of the fuel is diverted and burned in the turbine that drives the pump. But, at startup you need to spin up these turbines in the first place. That is about 100,000 horse power before they are functioning. So, by using the energy of vaporizing liquid fuels, as shown here, to drive the pumps they can get enough spin to get enough fuel to start the burning of fuel that runs the rocket.

It's safer to handle liquid nitrogen without gloves because of the Leidenfrost effect. The ultracold nitrogen will slide over your skin instead of freezing the glove and make it stuck to your hand.
@@MarianLuca-rz5kk same thing. Sweat over your skin will protect you from object that are too cold or too hot. Even lava can bounce on your skin if it was a small droplets

It'd probably be a function of sublimation of N2 in room temperature air along with treating the bottle opening as a smooth pipe, then an iterative calc for the expulsion of water with a pressure max as the last water exits. It sounds a little too complicated for a closed form functional, but easy enough for an undergrad to code up.
you wouldn't have to worry about it, if it got onto your hand you have a couple seconds to turn your hand upside down and have 0 damage (as it wouldn't touch your hand due to the leindfrost effect)
Always best to test, work out the kinks, and get it right a few times in a row before you do the demo. I know of a lab that was working on a special device for the Navy. It was kind of like a gun, but with no projectiles. It had a firing chamber and a short "barrel". According to the plan, submerged in a captured harbor, controlled from a minesweeper ship, a charge in the firing chamber of the device would go off, and create an underwater shock wave to clear obstacles and destroy mines, so friendly ships could use the harbor. Experiments began with one device, then later, 3 connected together in a battery, then a battery of 9 devices stacked on each other 3x3 like building blocks. A single device worked fine, gave "Proof of Concept". The battery of 3 worked well, each device reinforcing the power of the others. They built the 9-device 3x3 battery, but technical problems and supplier issues delayed completion to the point that there was no time for testing before the scheduled demonstration for "the brass". So they took it to a flooded quarry no longer in use, put it in the water, set it off, and it blew itself to pieces with the customer watching. The steel wasn't strong enough to withstand the force of 9 devices at once. If there had been testing first, they could maybe have redesigned and used stronger materials in a 2nd build. But they blew it up in front of the client; and I think that was the end of that particular project. So yeah; you iron out the bugs before you do the demo.
These days, scientists are just getting crazier with liquid nitrogen
😂😂
these days scientific uses fahrenheit 😂
This is nothing new though...

What does 320 degree mean? Absolute zero temp is 273.15 °C.
