Dr. David Little, an Oakville physician, had the substance tested as well and stated it contained human cells that remarkably possessed no nuclei. Moreover, the substance contained two types of bacteria, one of which is also found in the human digestive tract.
Some theorized that military bombing tests some fifty miles out to sea could have flung jellyfish filled sea water into the clouds where it somehow managed to stay suspended long enough to travel inland and rain down on the locals. And contain human cells. And I'm not buying that one either.
Even if you discount the human cells stuff, the prospect of those blobs staying suspended for any length of time without the presence of violent updrafts (as accompanied with thunderstorms) is a hard one to swallow.
So we chalk this up to another one of the weird Fortean falls that goes unexplained but not forgotten.
