I'm looking for the title of a science fiction B movie which I saw very long ago for which I have only a fragmentary memory: a lab worker is covering a bell-jar like contrivance which is encaging two small, glowing and bobbing spheres of some un-nameable plasma (creatures...?!). She leaves the darkened room, and the guys working the baby spot - I mean, they escape, wending their eerie way around the eerily lit lab....and the memory ends. What film is it?
