Compass & Current

I connected two D-cell batteries to wires and a folded strip of aluminum foil. This makes a "short circuit" that provides lots of current -- which is why you see I don't leave it connected very long. The aluminum foil part of this circuit fits nicely under my clear compass, so you can see what electric current does to the magnet of a compass.
