Lightning: So Frightening
What is lightning? What warning signs does lightning give? Does a lightning flash travel upwards or downwards? Why does lightning flicker? Why isn't it a good idea to lie down on the ground when there is a thunder storm around? Why does lightning sometimes kill but at other times does not? Why do so many people die unnecessarily after being struck by lightning? What causes thunder, and why does it rumble? Who holds the world record for the total number of times being struck by lightning and surviving, and what happened to him on each occasion? See the strong spark from a Leyden jar, even longer sparks from a one-half-million-volt Tesla coil, the effect of electricity on the muscles of students (ouch!!), how lightning caused an Italian church to explode, what happens when lightning strikes a car, and more, and hear some fascinating stories involving lightning. |
Study how Benjamin Franklin determined the nature of lightning, how and why lightning affects the human body, the concept of the lightning rod (including its application in the lightning rod umbrella), different types of lightning strikes to people and other animals, ways to protect yourself from being struck by lightning (including safe places to be during an electrical storm, a common misconception about why being in a vehicle can protect you from lightning, and why lightning can affect an oak tree more than a gum tree, and come away with a very much heightened appreciation of the dangers of lightning.
