Run exactly as fast as a 9mm bullet and, to you, it just floats there. Relative velocity zero. Easy catch… right?
Not quite. Rifling spins a pistol bullet at almost 90,000 RPM, so even a “stopped” bullet is still a tiny drill.
A thought experiment: nobody can actually run at 1,200 feet per second.

If you could run 1,200 feet per second, would you still try to grab it? 🤏👇
move your hand at the same speed as the bullet's rotation to catch it
What if you were spinning at the same speed too
