(CNN) -- It wasn't exactly Disney magic.
It seemed more sinister at the time, when a trash can exploded at Disneyland on Tuesday evening, prompting the evacuation of the Mickey's Toontown section for a couple of hours.
"Upon initial investigation, it appears it was a plastic bottle with dry ice in it that had exploded," said Sgt. Bob Dunn of Anaheim Police Department in California.
The development left visitors startled and a bit shell shocked.
"Just a big boom and the trash can exploding ... the lid coming up ... people were at a standstill," Vanessa Vasquez told CNN affiliate KCBS. "It was kind of a little scary when I saw the whole area (look like a) ghost town."
Others said the sound is a rarity in the area.
"It was very tense at the moment it happened because you don't expect to hear that sound at Toontown," said Allen Wolf, another Disney visitor.
"In an abundance of caution, the area was evacuated," Disneyland said on its official Twitter account. "There were no injuries and no reported damage."
Toontown got the all clear to reopen a few hours later.
