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.


Mantis shrimp punches travel 12 to 23 meters per second (approximately 27 to 51 miles per hour) in water the acceleration involved can reach up to 10,000 Gs.
The peak force generated by a mantis shrimp’s punch can be as high as 1500 Newtons, which is over 2500 times the animal’s own body weight.
The acceleration of their punch is such thay it creates a cavitation bubble which, when it collapses, can generate 8,500 degrees Fahrenheit – nearly as hot as the sun’s surface at 10,000 degrees Fahrenheit.
We named ours Smeagol.
The Mantis Shrimp is one of the few things that make me question pure raw evolution. How the fuck can you just evolve a sci fi plasma pistol?
