In Medieval times, the drowning test was a popular method to prove if a woman was a witch. If you dunked a woman and she floated she was a witch and would be hanged. If she sank she was innocent but sadly dead.
Today we have the US Air Force.
The Air Force recently rejected a woman’s medical exemption for the experimental COVID vaccine. She will be forced to take the vaccine to see if she has a real allergic reaction to its ingredients.
