Many tongues have been injured by licking a piece of metal on a very cold day. Why would no harm result if a piece of wood were licked on the same day? @Abhisar

OpenStudy (anonymous):

ah, because by licking wood, there is a less likely of a chance that your tongue will freeze to it on a cold day

OpenStudy (abhisar):

why ?

OpenStudy (anonymous):

because wood does not freeze the same way metal does and when something warm such as your tongue touches a cold piece pf wood your tongue will not stick to it that it one of the reasons they use wood for popsicle sticks

OpenStudy (abhisar):

No, it's a myth

OpenStudy (abhisar):

nothing to do with stickiness

OpenStudy (anonymous):

what part is a myth

OpenStudy (abhisar):

Metal is a good conductor of heat whereas wood is bad conductor. So when u lick a cold metal stick or something then it will rapidly suck the heat/warmth of delicate blood vessels present in the tongue. This will cause a frostbite and injure ur tongue

OpenStudy (abhisar):

If u lick the wooden stick it will not conduct heat, so the tongue will be unharmed

my step daughter has gotten her tongue stuck to a metal gate post here because she licked it and it was cold outside (winter) and we had to use warm water to get it off and she had a few sores on her tongue

OpenStudy (anonymous):

ok so the myth is licking wood will not injure the tongue at all because wood is not a conductor of heat

OpenStudy (abhisar):

yep !!

OpenStudy (anonymous):

got it

OpenStudy (abhisar):

Cold metal sticks to tongue because it freezes the(thin) layer of saliva that coats your tongue. So you now have a layer of ice between your tongue and the object, and both your tongue and the object are stuck to the layer of ice.
