@gambrel saidIn the biology lab at my grammar school there was a jar with a tiny embryo in it. We used to look at it through the locked glass cabinet door. Goodness knows how the poor thing was obtained. I doubt that would be allowed now?
Our entire universe and beyond is inside a Mason jar, sitting on a shelf in a 9th grader's bedroom. It's a 2 year old science fair project, it got 4th place.
