The ions don't need to be felt by anything. The force of the ion moving in one direction accelerates the object in an equal and opposite direction. If you could fart out the window of a spacecraft you would physically move the craft.
The atmospheric pressure is the pounds of pressure the air around us on earth or any planet is pressing down ward at any point. It is different as sea level and Denver.
It took sending the military to think of that?
destroying government property will get you a rubber bullet.
Is Forged In Fire coming back on?
damn what day they move it to?
It is not an electron until observed - then the mass-less quantum wave (of the EM wave) collapses into a photon with mass.
opps I got that wrong the photon may be mass less - but the observation and collapse of the EM wave excites an electron with mass into a higher orbit that releases a photon.
