Oil Prices Plummet, Lowest in Six Years

Oil prices have started falling again. U.S. oil =hit the $43 a barrel range, the lowest in six years.

Gas prices have stopped climbing, with the national average at $2.40 a gallon.

Some experts think gas prices could fall back to around or below $2 a gallon.

Analysts say there's still just too much oil on the market for prices to go back up.
