BTW, that whole spraying the battery of a kaplooey bomb with liquid nitrogen is not the way it's done. The normal procedure is to spray the electronics so they cease to function and cannot trigger an explosion. The show implied that the bomb would not blow because there was insufficient power in the battery to trigger the explosion. If true, they could have simply placed a shorting wire across the battery terminals when the battery was frozen (since it would have had no voltage), removed the battery, and voila', no explosion. Indeed, you need a lot less coolant to keep the electronics cool because they have so much less mass than that huge battery did. I'm jes' sayin'.
