what u doing with liquid nitrogen man?! sounds interesting, if painful
We have dewars which we fill from a mahooosive tank outside the building, they get used for our thermal vacuums to cool stuff down to simulate being in space.
Normally you can pour a small amount on your hand and it evaporates before it touches you, but it comes out this hose like a firemans hose :crazy:

in case anyone wants to know what a dewar is (as I didn’t until today)
Liquid Nitrogen Dewars – SPI Supplies

Urm has a few big warning signs, also it is pretty hench safety gear I am supposed to wear. Never had any issues in the past so became a bit complacent about the procedure! It was at 8am this morning and I was to engrossed in texting so I had my head up my arse! Looks like I got away very lightly with it and I have learnt a big lesson….
I never imagined a cold burn could be as bad as they are, suppose the way to look at it is that you fry chips at about 180 degrees and LN2 is -192 degrees. treated it like I would a normal burn so suppose that helped a lot
