...our professor introduced us to LN2, he poured some into an insulated container, dipped in a rose, the LN2 boiled and bubbled over, he took out the rose and smashed in on the lab bench - it shattered...very impressive...

There is a High School chemistry professor who hosts a cook out last day of the school year. He pours about 3 gallons of liquid oxygen into a full bag of charcoal in a Weber kettle with only one briquette burning. The resulting flare up burns all the charcoal and the grill completely in seconds.

As to be expected, YouTube has a vid:

I don’t drink anymore, but it would seem that you are supposed to wait before drinking this stuff down. Would you drink it while it was still smoking? Maybe she was already drunk and just didn’t think about what she was doing.

A life forever changed because of alcohol.

That’s probably a pretty impressive demonstration! That one might be a little over-the-top for me, liquid oxygen is not a material I’d really feel comfortable having around even a single lit piece of charcoal...

In grad school, there was a student that dropped a standard gas cylinder while moving it with the protective top off, it hit the edge of a bench, knocked off the regulator and top, the cylinder went though a block wall on the second floor and ended up in a car in the parking lot below...I didn’t see it happen, but I did see the aftermath...granted, that is a little off topic as (if I remember correctly), that was argon and the resulting destruction had nothing to do with flammability (argon is a noble gas), just the fact that 2200 psi is nothing to mess with...

I’ve heard of foods being prepared with LN2, and I’m sure that’s an accepted process...the ‘Dots’ ice cream you see at amusement parks are made with LN2, but they’re not serving it at -196oC!
