    I'm just trying to figure out what force I'm creating here. I have been testing a new idea and I can't put my finger on it. It acts different in a chamber then outside it but it acts the same with a vacuum or without in the chamber. I know it's not pretty but I don't want to spend a lot on it right now. Any ideas would help? Thanks

    Your "vacuum" isn't a vacuum.

    If there were no atmosphere then there'd be no movement of the paper(?) when the device spins.

    As for the comment "it's not atmosphere either" - if it's not a vacuum then, by definition, it is "atmosphere" (i.e. there is gas present).

    Please, specify exactly what YOU mean by "atmosphere" (since, apparently, the actual definition doesn't suit your preconceptions).

    The spinning device moves the air that's in the jar (i.e. the atmosphere) which in turn moves the paper.

    For reference you (or whoever is in that video) quite clearly state "about 15 inches" (presumably of mercury). That 15 inches equates to somewhere around 16-17kft of altitude on Earth (see chart) where there is enough atmosphere for flight and combustion (that's why engines work at those altitudes). It's also roughly 70 timers denser than the atmosphere on Mars (and Mars does have what is called an atmosphere). And, it should be noted, the atmosphere on Mars is quite capable of picking up and moving particles, which is why it has dust storms.

    Sorry for the multiple replies I tried replying once and it kept saying error. I get that it's not a vacuum that we would want. But it does the same thing inside the jar with pressure or less. When it does something different is when it's outside of the jar. It moves things towards it instead of pushing it to the edge. The only other thing is jet engines can fly up there but they have air going in and then air going out. When I place this one just in a tube it tries to pull objects in only.

    Of course: the bottle itself constrains the air flow and the movement of the paper.

    Because it's a closed environment.
