A giant magnet is slowly making its way along the Mississippi River.  The red, ring-shaped electromagnet is called the Muon G-2 and it's on its way from the Brookhaven National Laboratory in New York to a lab in Chicago.  The magnet helps scientists find tiny, undiscovered particles.

It's being pulled by a barge at a rate of just seven-miles-an-hour.  The 50-foot-spent most of the day Thursday passing through the St. Louis area, entering the Mel Price Lock & Dam at about 3:30pm. The last leg of its journey to Chicago will be over land.
