When you put a bananna into liquid nitrogen why doesn't it shatter?

Cut it open. I'm guessing it didn't freeze completely. I had a banana in liquid nitrogen for 5 minutes or so, and the inside was still unfrozen! Those things are good insulators...

Obviously, if it wasn't frozen all the way through, it would not be very brittle, as this occurs in plant material (such as flowers) when the water inside of them freezes.

it might desire to be a fabric that the two does not become brittle or continues to be sufficiently reliable at quite low temperatures. i think that particular metals like tungsten or titanium does not quite shatter if hit difficult after being dipped in liquid nitrogen, in spite of the fact that their fabric residences would exchange severely on the low temperature.

I put my wee-wee in liquid nitro once, that's kind of like a bananna, thank God it didn't shatter!

Bananas are meant to be eaten not frozen and get smashed. That's why.
