lightning rod Scientific  

1. A grounded metal rod placed high on a structure to conduct electrical current from a lightning strike directly to the ground, preventing the currents from injuring people or animals or from damaging objects. Lightning rods usually have a sharp, pointed tip, since electric lines of force are more highly concentrated around pointed objects, in this case increasing the attractiveness of the rod compared with other nearby objects.

2. See also Saint Elmo's fire
