Many, many years ago, Ben Franklin proved lightning was electricity. Franklin and his son flew a kite into a violent storm with a key attached to the kite’s string while he held on.
Luckily only the key was charged by the high voltage strike. Today we know a lightning strike’s temperature is hotter than the sun’s surface. It is no wonder Franklin’s key glowed in the aftermath of the storm.
Keep that thought in mind as we answer my wife’s question asked after an unusually loud thunderclap. “What is that and what causes thunder? Is it dangerous?”
