I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.


That’s probably the fastest thing a human body by itself can produce…
Modern MLB pitchers can regularly throw a baseball 100+ mph. Currently, the flick of the wrist during a curveball throw is the fastest human motion recorded.
Some viruses particles explode out of cells with crazy force. I don’t know it off the top of my head but I remember reading about that somewhere.
…but nobody has measured my farts yet.
