I'd tell you my players are crazy, but that would be redundant at this point. On one hand the wizard in the 4e game has found the clockwork bombs in the Player's Guide to Eberron. On the other hand we don't play in any modern settings so nuclear weaponry is currently out of their reach. Not that I expect that to stop them from creating massive explosions.
