… while they were in your pants pocket?

Yesterday on our road trip I started feeling this burning sensation in my pocket … I thought at first it was the sun coming through the car window, but it kept getting warmer and warmer. Then I stuck my hand in my pocket (I think this is still legal in the hands-free era) and noticed all the coins in there were burning hot, then I noticed the extra pair of AA rechargeable batteries there was hottest of all.

Everything cooled down after I took it out of the pocket. The only explanation I could imagine was that somehow the coins had closed the circuit between the poles of the batteries. Guess I’m lucky they didn’t catch fire or explode… that would’ve been great fun on a curvy mountain road.

Anybody ever hear of something like this happening?
