Liquid Nitrogen and Lava!

For years, people have asked for liquid nitrogen and lava. Today, on April 1st, we deliver!

No I meant the lava that came out of a volcano

I have a PhD in rocket surgery from the university of Chuck E. Cheese's, and I'm outraged by how little you value your safety. That lava looks really hot and would no doubt have caused serious bodily harm if lathered onto someone in a way that made them feel uncomfortable.

This is the first time I've seen liquid nitrogen more dangerous than lava

Wow it works! The dislike button works!!!

Did you guys really think that they would combine molten lava and liquid nitrogen in a computer lab on April Fool's Day?! 😑👈 Think...

*QUESTION*
I have wondered this for a while, maybe a possible experiment; Quenching supper hot steel in Liquid Nitrogen.

When hardening a tool, lets sat a knife, one heats it up to about a cherry red, up to the point where it no longer acts magnetic (any hotter and the grain structure grows and weakens the blade), and then quenches it in a bath of oil. From there the blade is partially annealed to bring it down from max hardness to the desired hardness. I am not sure if this is correct, but I have heard that the faster the blade cools, the harder it can be up to a limit. The ideal hardness would therefor be shown as a limit on an exponential graph, the faster one can cool it, the closer it will be to the limit.

I have heard of companies doing a sub-zero quench, but to my knowledge they are only using supper cooled oil that is not even close to the temperature of LN2.

I wonder if the steel would actually cool faster at all, maybe the Leidenfrost effect would be so great the steel would not get that instant drop in energy as it would with supper cooled oil.

Get trolled, that was the best minecraft squeaker trolling lets play I've ever seen

I was wondering how you were keeping molten lava in that aluminum/glass container.

You guys are right of what we didn't expect at all, but I do like the punnery in this vid. lol

I know real lava would be cool to watch but I am not sure they are equipped to handle that kind of experiment in the classroom. Having worked with molten things like steel and even rock, and then using nitrogen for contracting metal set pins and very tight fitting metal parts, I know that the explosion that would take place is nothing to be around when those two extremes come together, not just because of temperatures but the rapid chemical reactions that DO take place. I am sure they want to live to see another day

You guys must be cool teachers... what grade levels do you both teach?

I will say what it should have happened with real lava.
Lava is molten rock so if they put it in liquid nitrogen, it would have cooled, becoming solid rock again.
Am I right?
