00:00 Roy Sullivan, a park ranger at Shenandoah National Park, holds the record for being struck by lightning seven times.

04:35 Between 90% and two thirds of people who are struck by lightning survive, and men are four times likelier than women to be struck by lightning.

09:09 Lightning is formed through a process of cloud formation and charge separation, where positively charged particles accumulate at the top of the cloud and negatively charged particles accumulate at the bottom, creating an electric field that eventually results in a discharge of electricity.

13:24 Lightning can occur within a cloud or between clouds, and it is caused by the ionization of air and the creation of conductive channels that allow electricity to flow.

17:36 Lightning is caused by the formation of plasma channels that stretch up from the ground or other objects and connect with the streamers coming down from the sky, resulting in a sudden current exchange between the cloud and the earth, which produces a tremendous amount of heat energy and an explosion of air that creates thunder.

21:43 The distance between lightning and thunder can be estimated by dividing the number of seconds between the two by five, as the speed of light is much faster than the speed of sound.

26:02 There are various types of lightning, including ground to cloud, cloud to ground, sheet lightning, heat lightning, and ball lightning.

30:17 Ben Franklin developed lightning rods in the 1740s, which are metal rods on the roof of a building that divert or collect lightning strikes to prevent damage, and lightning rods do not attract lightning but offer a path of least resistance. Seeking shelter in a car during a lightning storm is a good move because cars act as Faraday cages, protecting the occupants from lightning strikes.

34:30 To protect yourself from lightning strikes, it is important to avoid standing under trees, climbing flagpoles, and touching the ground with anything but the bottom of your shoes, as lightning can send an electrical current across the ground and cause neurological damage or even death.

39:01 Lightning can cause burn wounds at the point of entry and exit, and the reason it doesn't kill people all the time is because the shock happens so fast that it doesn't have the same amount of time as an industrial electrocution to cause severe damage.
