Surely everyone out there accidentally detonates their MP3 player from time to time, right? I know I do. The YoTank MP3 player cases are milled from solid blocks of aluminum and can stand a RPG or mortar shell explosion 85 percent of the time. Jokes aside this is actually a good invention for our troops serving overseas that treasure their MP3 players. They make cases for the iPod nano, video, mini and the Creative Zen Vision:M. Prices range from $35 to $75.
