actually i heard that there is a new swam cartel in town which is buying up all the naturally produced swams so as to create artificial rarity. now all they need is to put some ads on the television that convince us that to show our love to our soon-to-be/current wives we need to purchase one of these.
liquid nitrogen is extremely cold, but you can stick your finger in it, or pour it on yourself, etc. i have done this in various physics labs. the idea is that it boils at such a low temp that it wont be able to freeze to your body, or let alone touch it, because your body heat is warm enough to boil it quick enough that there will always be a layer of N2 gas around your skin. so your finger will feel a bit cold, (actually warmer than it would if you put it on a block of ice) but you will definately not lose any part of it. i also had a physics prof who would swallow a piece of dry ice and burp up the smoke-looking gas.

actually all you need is to continually conduct endothermic reactions to produce the liquid N2, therefore the first law of thermo wouldn't be broken.
