Happy 241st, America! (part one)

It's a gun, not a duck. All sounds will echo, depending on the circumstances.

Umm...yes they do. The physical properties of sound waves don't change. However for the given decibel level a gun shot will have a more distinctive crack sound than the pop of a firework.

That's what I meant

But how

Some guy shot his gun in the air and well you know the bullets eventually gotta come down some time

Ah, makes sense
