Electron Gun
Is there any tiny particle gun such that we can't feel or hear the shots?

How big would the micro/nano/electron gun have to be since mass is tiny? This Q just for stable paritcle (not lazer, etc.!).
My guess is F=ma => 'a' has to be big. Not sure. Thank you.

We have electron guns. You wouldn't feel or hear them. It would be hard to make a gun that uses gun powder that shoots a small enough particle that you couldn't feel it. But it is not at all hard to make guns that shoot using something other than gun powder (like electric fields or heat) that shoot very very small things.
