Welcome to the
|Ball lightning reportedly takes the form of a short-lived, glowing, floating object often the size and shape of a basketball, but it can also be golf ball sized or smaller. It is sometimes associated with thunderstorms, but unlike lightning flashes arcing between two points, which last a small fraction of a second, ball lightning reportedly lasts many seconds. There have been some reports of production of a similar phenomenon in the laboratory, but some still disagree on whether it is the same phenomenon.|
Are there images of ball lightning?
Interesting atmospheric phenomena is occasionally captured on film or video, here is an example:
Here is a very interesting video; a team in Brazil has cooked up a simple recipe for making similar eerie orbs of light in the lab, even getting them to bounce around for several seconds...
We highly recommend visiting the WEIRD SCIENCE PAGE database of BALL LIGHTNING REPORTS for an exhaustive list of eye witness accounts.
