Allegedly this is a white blood cell chasing around some bacteria and eventually subduing it. Of course, I have no proof that's actually what this is because I'm not a microbioscientist. For all I know it's a really bad VHS copy of a Benny Hill chase scene from the end of his show. But where's the music? A DOO DOO DOOTLE OOT DOO DOO DOOTLE OOT DOOT DA DOOT DA DOOT DOOT. Oh yeah, that's the stuff.
Thanks to Ian, who destroys bacteria like colloidal silver. Haha, I know science!
