I heard on the news this morning that a portion of the Toontown area in Disneyland was closed after an explosion occurred in a trash can. According to my local news station Disney cast members blocked off the area while police and bomb squads investigated the trash car. It seems like there was some dry ice in a bag or a bottle that caused the explosion. No one was hurt and the area re-opened some time later that day.
Ill try to link to a story in I can find one.
EDIT:
Found a story on the explosion.
