A high-speed camera captured lightning striking residential buildings in Brazil, revealing new details about such strikes. The spectacular slow-motion video shot at 40,000 frames per second shows the connection process between lightning and a building. The video also shows that a staggering 31 fingers of upwards reaching lightning, called positive leaders, launched upwards from other nearby buildings in an attempt to intercept the downward negative leaders. The strike severely damaged a chimney, throwing fragments in all directions, the researchers report.
