the guy Posted July 10, 2011 Share Posted July 10, 2011 for a short story i'm writing; what would happen if someone's finger was submerged in -25 degrees C liquid? would it freeze enough to smash it or would it just kill it or what? Link to comment Share on other sites More sharing options...
rktpro Posted July 10, 2011 Share Posted July 10, 2011 Fingers would become useless/dead and so the hand. I heard Bear Grylls say so. 1 Link to comment Share on other sites More sharing options...
CharonY Posted July 10, 2011 Share Posted July 10, 2011 Depends on the length of exposure. First thing is numbness then frostbite. Eventually the finger dies off. I doubt that with -25° you are able to make tissue so brittle that it breaks easily. Maybe after very long exposure you may find stress fractures (my guess is that you require lower temperatures, though, maybe -40). There are likely to be reports from expeditions with details, though. Also, I wold not try it out, as much as one might encourage experimental validation.

the guy Posted July 11, 2011 Author Share Posted July 11, 2011 ok thankyou, and don't worry i do not intend to try this, it's bad enough sticking your finger in 0 degrees water! Link to comment Share on other sites More sharing options...
xxSilverPhinxx Posted July 12, 2011 Share Posted July 12, 2011 (edited) If you freeze it quickly before giving it time to die, it might become brittle. The ice crystals would break the cell structure from the inside when they expand. Edited July 12, 2011 by xxSilverPhinxx Link to comment Share on other sites More sharing options...
