Raining oil? A video purports to show the aftermath of an oily rain that has left a rainbow sheen on the streets of River Ridge, Louisiana. The EPA says that an oily rain is highly unlikely.
It's unclear from the video whether the oily sheen seen on the ground really fell from the sky. Crude oil normally doesn't evaporate, but some are speculating that oil mixed with Corexit 9500, the dispersant that BP is using on the ever-growing slick, could take to the air.
The US Environmental Protection Agency has issued statements saying that the agency "has no data, information or scientific basis that suggests that oil mixed with dispersant could possibly evaporate from the Gulf into the water cycle."
