A small explosion in a Disneyland trash can that appeared to be caused by dry ice in a bottle brought evacuations but no damages or injuries, officials and witnesses said. The blast was reported in the Mickey\'s Toontown area of California Disneyland, Anaheim police spokesman Sgt. Bob Dunn said. Disneyland officials called the explosion \'a small bang,\' and said that \'in an abundance of caution, the area was evacuated.\' They said they were working with local authorities. Anaheim police investigated with assistance from an Orange County sheriff\'s bomb squad. About two hours after the explosion the review was completed, the area was deemed safe and guests were allowed to return to Toontown, Disneyland said. Mickey\'s Toontown, designed to make visitors feel like they\'ve entered an old-fashioned cartoon, \'is an interactive metropolis full of topsy turvy architecture and screwy sculptures,\' according to the Disneyland website.
