Oil is dropping dramatically:

World oil prices fell again on Wednesday, deepening a five-day rout that has knocked 21 percent off the cost of a barrel as dealers brace for an impending U.S. invasion of Iraq.

Prices have tumbled $8 in the last five trading days as dealers bet hard on an easy U.S.-led victory in military action they expect to cause only a brief disruption to Middle East oil flows.

How fast will the price of gas drop?
