Hi all Since many discuss ways to self-inflict damage through dry ice for the doctors to amputate a hand in the hospital, I would like to know how long it should be enough holding a hand with dry ice for the hand to be amputated and how much i must froze the hand (height of the hand) to avoid losing less or more I do not know for example: if we apply ice only to the hand, to where the damage will extend outside the hand. Can we use the ice that is sold in a bag for whiskey
