Ball Lightning Punches Circular Hole In Window

Window glass with hole created by ball lightening
Window glass with a 7-centimeter hole fitting glass circle believed to have been created by ball lightening.
In the Autumn 1992 issue of the Journal of Scientific Exploration, A.I. Grigor'ev et al collected 43 eyewitness accounts of ball lightning penetrating into closed rooms. Most of the reports came from the former USSR and are new to Western scientists.

The majority of these balls entered through closed glass windows. Sometimes the balls penetrated the windows without damaging the glass at all, but in a few cases neat circular holes were somehow melted or punched through the glass. The accompanying photograph illustrates an incident in which lightning (supposed to be ball lightning) surgically excised a coin-like piece of glass.
