A Mystery of Nature —Ball Lightening
1- During a thunderstorm, a glowing ball the size of your head suddenly appears. It hovers a few feet above the ground, drops down, dances across the yard, and then darts up into the air before it fades away.
2- This freaky phenomenon is ball lightning.
3- Sometimes it disappears with a small explosion.
4- Some scientists think that when normal lightning strikes the ground, it vaporizes a mineral called silicon found in soil.
5- They think this silicon forms a kind of bubble that burns in the oxygen around it.
6- But Nevertheless Ball Lightning is still an unexplained atmospheric electrical phenomenon.
7- Many of the early reports say that the ball eventually explodes, sometimes with fatal consequences, leaving behind the odour of sulfur.
8- Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon.
9- One Main reason for the phenomenon still unknown is the lack of Scientific knowledge and its inconsistent appearance.
10- Its existence is mostly based on reported public sightings, and has therefore produced somewhat inconsistent findings.
11- Given inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown.
