Electricity was discovered by the first guy looking at a thunderstorm, so they were called "thunder fish".
The word "electricity" was invented to describe the property of attracting straws after rubbing some wool on an "electron", which was associated with "sunbeam" and was the Greek word for amber (which in turn got its name after people conflated the ambergris or "gray amber" derived from sperm whales, with the fossilized tree resin or "yellow amber"... and the whales got their name from whale oil or "spermaceti"... which yes, people thought was whale semen that just happened to burn great in candles).
PS: blow the candle and sweet dreams... ๐ฌ๏ธ๐ฏ๏ธ
