I'm not sure where to put this, Its exactly what the title says: this one shows the grape more clearly, starts properly about 1 minute in, and also quite long sustained plasma with a match, Plasma from a grape! any ideas how? or is it fake? also if you watch any of the other similar videos the sustained plasma is only created when there is a glass over it, why? could it be something to do with the resonant frequency of the glass? i noticed it seemed to be sustained longest in glasses with a circular curved bottom section, ones with right angled edges dont seem to work well.
