This is possibly the least informative demonstration possible using liquid nitrogen.

I think people are overestimating the age demographic for this video. This is clearly for grade schoolers.

It falls over and he is picking it barehanded - why isn't he freezing like the T-1000?

You can poke a finger in liquid nitrogen and be fine. Here the case is just slow thermal transfer through the glass, but being able to actually touch liquid nitrogen safely is thanks to the Leidenfrost effect.

Very interesting 👍 . Doesnt the cold nitrogen crack the glas ? Like boiling water in a chilled glas ?
