Gravity Doesn’t Exist
One girl in high school, let’s call her “Lisa,” honestly thought that gravity didn’t exist and the reason why we didn’t just float away was because of our weight.
Took about ten minutes to explain that gravity gave us our weight. She then proceeded to ask if gravity could, in her words, “Break like a pencil.” After explaining this impossibility, she finally stopped talking.
The very next day, she confused Newton with Al Gore. No joke. She was really nice, though.
