How can i heat little metal disks in my pockets. :)

i'd like a gizmo in my pocket that can heat up 3 quarters whenever i
want.
any ideas?
could it be as small as a box of wooden matches?
can anyone point me in the right direction?
any inventive minds that would like to work together to create a little
gizmo that will make coins hot in one's pocket drop me a line.
shouldn't be too hard.
if i'm in the wrong newsgroup for such a question, sorry.
Peace,
A

 

Why would you want to do that?

probably the easiest would be to short out a 9v battery with the coin.... I
know from experience of trying to carry a battery in my pocket with some
keys = very warm pocket.

How hot are you wanting the coins?

How about a small version of the chemical heaters used in the military.

If you live near Atlantic City New Jersey I have witnessed hundreds of
people with coins burning a hole in their pocket.

a nine volt wired to some type of coin clip sounds promising.
so does the chemical solution.
