Dry-ice "explosion" results in Toontown evacuation at Disneyland

Someone apparently put a sealed plastic bottle containing dry ice in a trashcan in Disneyland's Toontown yesterday. It made a loud noise (described by one witness as louder than a gunshot) and released some water vapor, and sparked an evacuation, which Disney describes as being the result of "an abundance of caution." No one was hurt and no damage was done. An employee was arrested for making what authorities have called a "bomb" but which also might be described as "a bottle that someone absentmindedly stuck some dry-ice in from an ice-cream trolley."
