This is definitely not recommended but when I was a kid we also used floppy disk films to look at solar eclipses. That was far from the most dangerous thing we did in 90s in a post-Soviet country.
To this day, when I read or think about a solar eclipse, I have a visual image of floppies! My first instinct seeing this on HN was “is this because there is a solar eclipse tomorrow?”
