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.
