We put it outside in a snow pile away from buildings, and by the end of the meeting it had melted a 3' radius in the snow. This was with the old style bateries, but regardless, you don't take chances with chemicals. Get rid of it! (recycled, of course)

Wow. That is really cool. Scary to think what would have happened if you kept it, but still cool.
