'Potential explosion' reported at Disneyland was show effects, authorities say

ANAHEIM, Calif. - A possible explosion reported at Disneyland Tuesday morning turned out to be testing for some effects used in the "World of Color" show, authorities confirmed.

Video shared with FOX 11 show a black-shaped cloud formed the air over an illuminated rollercoaster.
