I came across some photo's in the files of the late Dr Bill Collis titled 'Ball lightning' in a folder named Sochi 2005. I have asked a number of people and they are not sure what it is except maybe it's a hydrogen fireball. They look like a plasmoid in mid air without confinement, which is very interesting to me.
I would be interested if anyone knows anything about the experiment in the photos or who the person is in the photo's. Thanks in advance!
